  text: This is the second of three talks describing the observation and characterization
    of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
    to hexagonal boron nitride. I will compare the qualitative and quantitative features
    of this observed quantum anomalous Hall state to traditional systems engineered
    from thin film (Bi,Sb)2Te3 topological insulators. In particular, we find that
    the measured electronic energy gap of ~30K is several times higher than the Curie
    temperature, consistent with a lack of disorder associated with magnetic dopants.
    In this system, the quantization arises from spontaneous ferromagnetic polarization
    into a single spin and valley moiré subband, which is topological despite the
    lack of spin orbit coupling. I will also discuss the observation of current induced
    switching, which allows the magnetic state of the heterostructure to be controllably
    reversed with currents as small as a few nanoamperes.

  and the ARO for their generous support of this work.

  text: This is the third of three talks describing the observation and characterization
    of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
    to hexagonal boron nitride. In this segment I will present scanning probe magnetometry
    data acquired using a nanoSQUID-on-tip microscope, which provides ~150 nm spatial
    resolution and a field sensitivity of ~10 nT/rtHz. We study the distribution of
    magnetic domains within the device as a function of density, magnetic field training,
    and DC current. Our data allow us to constrain the magnitude of the orbital magnetic
    moment of the electrons in the QAH state. Comparison with simultaneously acquired
    transport data allows us to precisely correlate single domain dynamics with discrete
    jumps in the observed anomalous Hall signal.

  text: Partially filled Landau levels host competing electronic orders. For example,
    electron solids may prevail close to integer filling of the Landau levels before
    giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
    we report the observation of an electron solid with non-collinear spin texture
    in monolayer graphene, consistent with solidification of skyrmions3—topological
    spin textures characterized by quantized electrical charge4,5. We probe the spin
    texture of the solids using a modified Corbino geometry that allows ferromagnetic
    magnons to be launched and detected6,7. We find that magnon transport is highly
    efficient when one Landau level is filled (ν=1), consistent with quantum Hall
    ferromagnetic spin polarization. However, even minimal doping immediately quenches
    the magnon signal while leaving the vanishing low-temperature charge conductivity
    unchanged. Our results can be understood by the formation of a solid of charged
    skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
    Data near fractional fillings show evidence of several fractional skyrmion solids,
    suggesting that graphene hosts a highly tunable landscape of coupled spin and
    charge orders.

  text: We consider the sum of two large Hermitian matrices A and B with a Haar unitary
    conjugation bringing them into a general relative position. We prove that the
    eigenvalue density on the scale slightly above the local eigenvalue spacing is
    asymptotically given by the free additive convolution of the laws of A and B as
    the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues
    and optimal rate of convergence in Voiculescu's theorem. Our previous works [4],
    [5] established these results in the bulk spectrum, the current paper completely
    settles the problem at the spectral edges provided they have the typical square-root
    behavior. The key element of our proof is to compensate the deterioration of the
    stability of the subordination equations by sharp error estimates that properly
    account for the local density near the edge. Our results also hold if the Haar
    unitary matrix is replaced by the Haar orthogonal matrix.

  text: "We introduce the notion of Witness Maps as a cryptographic notion of a proof
    system. A Unique Witness Map (UWM) deterministically maps all witnesses for an
    \  NP  statement to a single representative witness, resulting in a computationally
    sound, deterministic-prover, non-interactive witness independent proof system.
    A relaxation of UWM, called Compact Witness Map (CWM), maps all the witnesses
    to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive
    proof-system. We also define a Dual Mode Witness Map (DMWM) which adds an “extractable”
    mode to a CWM.\r\nOur main construction is a DMWM for all   NP  relations, assuming
    sub-exponentially secure indistinguishability obfuscation (  iO ), along with
    standard cryptographic assumptions. The DMWM construction relies on a CWM and
    a new primitive called Cumulative All-Lossy-But-One Trapdoor Functions (C-ALBO-TDF),
    both of which are in turn instantiated based on   iO  and other primitives. Our
    instantiation of a CWM is in fact a UWM; in turn, we show that a UWM implies Witness
    Encryption. Along the way to constructing UWM and C-ALBO-TDF, we also construct,
    from standard assumptions, Puncturable Digital Signatures and a new primitive
    called Cumulative Lossy Trapdoor Functions (C-LTDF). The former improves up on
    a construction of Bellare et al. (Eurocrypt 2016), who relied on sub-exponentially
    secure   iO  and sub-exponentially secure OWF.\r\nAs an application of our constructions,
    we show how to use a DMWM to construct the first leakage and tamper-resilient
    signatures with a deterministic signer, thereby solving a decade old open problem
    posed by Katz and Vaikunthanathan (Asiacrypt 2009), by Boyle, Segev and Wichs
    (Eurocrypt 2011), as well as by Faonio and Venturi (Asiacrypt 2016). Our construction
    achieves the optimal leakage rate of   1−o(1) ."

  text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
    materials are superimposed with a relative twist angle between them, the electronic
    properties of the coupled system can be dramatically altered. Here, we demonstrate
    that a similar concept can be extended to the optics realm, particularly to propagating
    phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
    composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
    phonon polaritons (PhPs), and image the propagation of the latter when launched
    by localized sources. Our images reveal that, under a critical angle, the PhPs
    isofrequency curve undergoes a topological transition, in which the propagation
    of PhPs is strongly guided (canalization regime) along predetermined directions
    without geometric spreading. These results demonstrate a new degree of freedom
    (twist angle) for controlling the propagation of polaritons at the nanoscale with
    potential for nanoimaging, (bio)-sensing, or heat management.

  text: In recent years, the nuclear pore complex (NPC) has emerged as a key player
    in genome regulation and cellular homeostasis. New discoveries have revealed that
    the NPC has multiple cellular functions besides mediating the molecular exchange
    between the nucleus and the cytoplasm. In this review, we discuss non-transport
    aspects of the NPC focusing on the NPC-genome interaction, the extreme longevity
    of the NPC proteins, and NPC dysfunction in age-related diseases. The examples
    summarized herein demonstrate that the NPC, which first evolved to enable the
    biochemical communication between the nucleus and the cytoplasm, now doubles as
    the gatekeeper of cellular identity and aging.

  text: Vascular dysfunctions are a common feature of multiple age-related diseases.
    However, modeling healthy and pathological aging of the human vasculature represents
    an unresolved experimental challenge. Here, we generated induced vascular endothelial
    cells (iVECs) and smooth muscle cells (iSMCs) by direct reprogramming of healthy
    human fibroblasts from donors of different ages and Hutchinson-Gilford Progeria
    Syndrome (HGPS) patients. iVECs induced from old donors revealed upregulation
    of GSTM1 and PALD1, genes linked to oxidative stress, inflammation and endothelial
    junction stability, as vascular aging markers. A functional assay performed on
    PALD1 KD VECs demonstrated a recovery in vascular permeability. We found that
    iSMCs from HGPS donors overexpressed bone morphogenetic protein (BMP)−4, which
    plays a key role in both vascular calcification and endothelial barrier damage
    observed in HGPS. Strikingly, BMP4 concentrations are higher in serum from HGPS
    vs. age-matched mice. Furthermore, targeting BMP4 with blocking antibody recovered
    the functionality of the vascular barrier in vitro, hence representing a potential
    future therapeutic strategy to limit cardiovascular dysfunction in HGPS. These
    results show that iVECs and iSMCs retain disease-related signatures, allowing
    modeling of vascular aging and HGPS in vitro.

  text: Aging of the circulatory system correlates with the pathogenesis of a large
    spectrum of diseases. However, it is largely unknown which factors drive the age-dependent
    or pathological decline of the vasculature and how vascular defects relate to
    tissue aging. The goal of the study is to design a multianalytical approach to
    identify how the cellular microenvironment (i.e., fibroblasts) and serum from
    healthy donors of different ages or Alzheimer disease (AD) patients can modulate
    the functionality of organ-specific vascular endothelial cells (VECs). Long-living
    human microvascular networks embedding VECs and fibroblasts from skin biopsies
    are generated. RNA-seq, secretome analyses, and microfluidic assays demonstrate
    that fibroblasts from young donors restore the functionality of aged endothelial
    cells, an effect also achieved by serum from young donors. New biomarkers of vascular
    aging are validated in human biopsies and it is shown that young serum induces
    angiopoietin-like-4, which can restore compromised vascular barriers. This strategy
    is then employed to characterize transcriptional/functional changes induced on
    the blood–brain barrier by AD serum, demonstrating the importance of PTP4A3 in
    the regulation of permeability. Features of vascular degeneration during aging
    and AD are recapitulated, and a tool to identify novel biomarkers that can be
    exploited to develop future therapeutics modulating vascular function is established.

  text: During mitosis, transcription of genomic DNA is dramatically reduced, before
    it is reactivated during nuclear reformation in anaphase/telophase. Many aspects
    of the underlying principles that mediate transcriptional memory and reactivation
    in the daughter cells remain unclear. Here, we used ChIP-seq on synchronized cells
    at different stages after mitosis to generate genome-wide maps of histone modifications.
    Combined with EU-RNA-seq and Hi-C analyses, we found that during prometaphase,
    promoters, enhancers, and insulators retain H3K4me3 and H3K4me1, while losing
    H3K27ac. Enhancers globally retaining mitotic H3K4me1 or locally retaining mitotic
    H3K27ac are associated with cell type-specific genes and their transcription factors
    for rapid transcriptional activation. As cells exit mitosis, promoters regain
    H3K27ac, which correlates with transcriptional reactivation. Insulators also gain
    H3K27ac and CCCTC-binding factor (CTCF) in anaphase/telophase. This increase of
    H3K27ac in anaphase/telophase is required for posttranscriptional activation and
    may play a role in the establishment of topologically associating domains (TADs).
    Together, our results suggest that the genome is reorganized in a sequential order,
    in which histone methylations occur first in prometaphase, histone acetylation,
    and CTCF in anaphase/telophase, transcription in cytokinesis, and long-range chromatin
    interactions in early G1. We thus provide insights into the histone modification
    landscape that allows faithful reestablishment of the transcriptional program
    and TADs during cell division.

  text: Nucleoporin 93 (Nup93) expression inversely correlates with the survival of
    triple-negative breast cancer patients. However, our knowledge of Nup93 function
    in breast cancer besides its role as structural component of the nuclear pore
    complex is not understood. Combination of functional assays and genetic analyses
    suggested that chromatin interaction of Nup93 partially modulates the expression
    of genes associated with actin cytoskeleton remodeling and epithelial to mesenchymal
    transition, resulting in impaired invasion of triple-negative, claudin-low breast
    cancer cells. Nup93 depletion induced stress fiber formation associated with reduced
    cell migration/proliferation and impaired expression of mesenchymal-like genes.
    Silencing LIMCH1, a gene responsible for actin cytoskeleton remodeling and up-regulated
    upon Nup93 depletion, partially restored the invasive phenotype of cancer cells.
    Loss of Nup93 led to significant defects in tumor establishment/propagation in
    vivo, whereas patient samples revealed that high Nup93 and low LIMCH1 expression
    correlate with late tumor stage. Our approach identified Nup93 as contributor
    of triple-negative, claudin-low breast cancer cell invasion and paves the way
    to study the role of nuclear envelope proteins during breast cancer tumorigenesis.

  text: We investigated the ultraviolet (UV) spectral properties of faint Lyman-α
    emitters (LAEs) in the redshift range 2.9 ≤ z ≤ 4.6, and we provide material to
    prepare future observations of the faint Universe. We used data from the MUSE
    Hubble Ultra Deep Survey to construct mean rest-frame spectra of continuum-faint
    (median MUV of −18 and down to MUV of −16), low stellar mass (median value of
    108.4 M⊙ and down to 107 M⊙) LAEs at redshift z ≳ 3. We computed various averaged
    spectra of LAEs, subsampled on the basis of their observational (e.g., Lyα strength,
    UV magnitude and spectral slope) and physical (e.g., stellar mass and star-formation
    rate) properties. We searched for UV spectral features other than Lyα, such as
    higher ionization nebular emission lines and absorption features. We successfully
    observed the O III]λ1666 and [C III]λ1907+C III]λ1909 collisionally excited emission
    lines and the He IIλ1640 recombination feature, as well as the resonant C IVλλ1548,1551
    doublet either in emission or P-Cygni. We compared the observed spectral properties
    of the different mean spectra and find the emission lines to vary with the observational
    and physical properties of the LAEs. In particular, the mean spectra of LAEs with
    larger Lyα equivalent widths, fainter UV magnitudes, bluer UV spectral slopes,
    and lower stellar masses show the strongest nebular emission. The line ratios
    of these lines are similar to those measured in the spectra of local metal-poor
    galaxies, while their equivalent widths are weaker compared to the handful of
    extreme values detected in individual spectra of z >  2 galaxies. This suggests
    that weak UV features are likely ubiquitous in high z, low-mass, and faint LAEs.
    We publicly released the stacked spectra, as they can serve as empirical templates
    for the design of future observations, such as those with the James Webb Space
    Telescope and the Extremely Large Telescope.

  text: "Context. The Lyα emitter (LAE) fraction, XLAE, is a potentially powerful
    probe of the evolution of the intergalactic neutral hydrogen gas fraction. However,
    uncertainties in the measurement of XLAE are still under debate.\r\nAims. Thanks
    to deep data obtained with the integral field spectrograph Multi Unit Spectroscopic
    Explorer (MUSE), we can measure the evolution of the LAE fraction homogeneously
    over a wide redshift range of z ≈ 3–6 for UV-faint galaxies (down to UV magnitudes
    of M1500 ≈ −17.75). This is a significantly fainter range than in former studies
    (M1500 ≤ −18.75) and it allows us to probe the bulk of the population of high-redshift
    star-forming galaxies.\r\nMethods. We constructed a UV-complete photometric-redshift
    sample following UV luminosity functions and measured the Lyα emission with MUSE
    using the latest (second) data release from the MUSE Hubble Ultra Deep Field Survey.\r\nResults.
    We derived the redshift evolution of XLAE for M1500 ∈ [ − 21.75; −17.75] for the
    first time with a equivalent width range EW(Lyα) ≥ 65 Å and found low values of
    XLAE ≲ 30% at z ≲ 6. The best-fit linear relation is XLAE = 0.07+0.06−0.03z −
    0.22+0.12−0.24. For M1500 ∈ [ − 20.25; −18.75] and EW(Lyα) ≥ 25 Å, our XLAE values
    are consistent with those in the literature within 1σ at z ≲ 5, but our median
    values are systematically lower than reported values over the whole redshift range.
    In addition, we do not find a significant dependence of XLAE on M1500 for EW(Lyα)
    ≥ 50 Å at z ≈ 3–4, in contrast with previous work. The differences in XLAE mainly
    arise from selection biases for Lyman Break Galaxies (LBGs) in the literature:
    UV-faint LBGs are more easily selected if they have strong Lyα emission, hence
    XLAE is biased towards higher values when those samples are used.\r\nConclusions.
    Our results suggest either a lower increase of XLAE towards z ≈ 6 than previously
    suggested, or even a turnover of XLAE at z ≈ 5.5, which may be the signature of
    a late or patchy reionization process. We compared our results with predictions
    from a cosmological galaxy evolution model. We find that a model with a bursty
    star formation (SF) can reproduce our observed LAE fractions much better than
    models where SF is a smooth function of time."

  text: We present spatially resolved maps of six individually-detected Lyman α haloes
    (LAHs) as well as a first statistical analysis of the Lyman α (Lyα) spectral signature
    in the circum-galactic medium of high-redshift star-forming galaxies (−17.5 >
     MUV >  −21.5) using the Multi-Unit Spectroscopic Explorer. Our resolved spectroscopic
    analysis of the LAHs reveals significant intrahalo variations of the Lyα line
    profile. Using a three-dimensional two-component model for the Lyα emission, we
    measured the full width at half maximum (FWHM), the peak velocity shift, and the
    asymmetry of the Lyα line in the core and in the halo of 19 galaxies. We find
    that the Lyα line shape is statistically different in the halo compared to the
    core (in terms of width, peak wavelength, and asymmetry) for ≈40% of our galaxies.
    Similarly to object-by-object based studies and a recent resolved study using
    lensing, we find a correlation between the peak velocity shift and the width of
    the Lyα line both at the interstellar and circum-galactic scales. This trend has
    been predicted by radiative transfer simulations of galactic winds as a result
    of resonant scattering in outflows. While there is a lack of correlation between
    the spectral properties and the spatial scale lengths of our LAHs, we find a correlation
    between the width of the line in the LAH and the halo flux fraction. Interestingly,
    UV bright galaxies (MUV <  −20) show broader, more redshifted, and less asymmetric
    Lyα lines in their haloes. The most significant correlation found is for the FWHM
    of the line and the UV continuum slope of the galaxy, suggesting that the redder
    galaxies have broader Lyα lines. The generally broad and red line shapes found
    in the halo component suggest that the Lyα haloes are powered either by scattering
    processes through an outflowing medium, fluorescent emission from outflowing cold
    clumps of gas, or a mix of both. Considering the large diversity of the Lyα line
    profiles observed in our sample and the lack of strong correlation, the interpretation
    of our results is still broadly open and underlines the need for realistic spatially
    resolved models of the LAHs.

  text: We report the spectroscopic confirmation of a new protocluster in the COSMOS
    field at z ∼ 2.2, COSMOS Cluster 2.2 (CC2.2), originally identified as an overdensity
    of narrowband selected Hα emitting candidates. With only two masks of Keck/MOSFIRE
    near-IR spectroscopy in both H (∼1.47–1.81 μm) and K (∼1.92–2.40 μm) bands (∼1.5
    hr each), we confirm 35 unique protocluster members with at least two emission
    lines detected with S/N > 3. Combined with 12 extra members from the zCOSMOS-deep
    spectroscopic survey (47 in total), we estimate a mean redshift and a line-of-sight
    velocity dispersion of zmean = 2.23224 ± 0.00101 and σlos = 645 ± 69 km s−1 for
    this protocluster, respectively. Assuming virialization and spherical symmetry
    for the system, we estimate a total mass of Mvir ∼ (1–2) ×1014M⊙ for the structure.
    We evaluate a number density enhancement of δg ∼ 7 for this system and we argue
    that the structure is likely not fully virialized at z ∼ 2.2. However, in a spherical
    collapse model, δg is expected to grow to a linear matter enhancement of ∼1.9
    by z = 0, exceeding the collapse threshold of 1.69, and leading to a fully collapsed
    and virialized Coma-type structure with a total mass of Mdyn(z = 0) ∼ 9.2 × 1014M⊙
    by now. This observationally efficient confirmation suggests that large narrowband
    emission-line galaxy surveys, when combined with ancillary photometric data, can
    be used to effectively trace the large-scale structure and protoclusters at a
    time when they are mostly dominated by star-forming galaxies.

  text: Ly α emission lines are typically found to be redshifted with respect to the
    systemic redshifts of galaxies, likely due to resonant scattering of Ly α photons.
    Here, we measure the average velocity offset for a sample of 96 z ≈ 3.3 Ly α emitters
    (LAEs) with a median Ly α flux (luminosity) of ≈10−17 erg cm−2 s−1 (⁠≈1042 erg
    s−1⁠) and a median star formation rate (SFR) of ≈1.3 M⊙ yr−1 (not corrected for
    possible dust extinction), detected by the Multi-Unit Spectroscopic Explorer as
    part of our MUSEQuBES circumgalactic medium (CGM) survey. By postulating that
    the stacked CGM absorption profiles of these LAEs, probed by eight background
    quasars, must be centred on the systemic redshift, we measure an average velocity
    offset, Voffset = 171\pm 8 km s−1, between the Ly α emission peak and the systemic
    redshift. The observed Voffset is lower by factors of ≈1.4 and ≈2.6 compared to
    the velocity offsets measured for narrow-band-selected LAEs and Lyman break galaxies,
    respectively, which probe galaxies with higher masses and SFRs. Consistent with
    earlier studies based on direct measurements for individual objects, we find that
    the Voffset is correlated with the full width at half-maximum of the red peak
    of the Ly α line, and anticorrelated with the rest-frame equivalent width. Moreover,
    we find that Voffset is correlated with SFR with a sub-linear scaling relation,
    Voffset∝SFR0.16±0.03⁠. Adopting the mass scaling for main-sequence galaxies, such
    a relation suggests that Voffset scales with the circular velocity of the dark
    matter haloes hosting the LAEs.

  text: CR7 is among the most luminous Ly α emitters (LAEs) known at z = 6.6 and consists
    of at least three UV components that are surrounded by Ly α emission. Previous
    studies have suggested that it may host an extreme ionizing source. Here, we present
    deep integral field spectroscopy of CR7 with VLT/Multi Unit Spectroscopic Explorer
    (MUSE). We measure extended emission with a similar halo scale length as typical
    LAEs at z ≈ 5. CR7’s Ly α halo is clearly elongated along the direction connecting
    the multiple components, likely tracing the underlying gas distribution. The Ly α
    emission originates almost exclusively from the brightest UV component, but we
    also identify a faint kinematically distinct Ly α emitting region nearby a fainter
    component. Combined with new near-infrared data, the MUSE data show that the rest-frame
    Ly α equivalent width (EW) is ≈100 Å. This is a factor 4 higher than the EW measured
    in low-redshift analogues with carefully matched Ly α profiles (and thus arguably
    H I column density), but this EW can plausibly be explained by star formation.
    Alternative scenarios requiring active galactic nucleus (AGN) powering are also
    disfavoured by the narrower and steeper Ly α spectrum and much smaller IR to UV
    ratio compared to obscured AGN in other Ly α blobs. CR7’s Ly α emission, while
    extremely luminous, resembles the emission in more common LAEs at lower redshifts
    very well and is likely powered by a young metal-poor starburst.

  text: A prediction of the classic active galactic nucleus (AGN) unification model
    is the presence of ionization cones with different orientations depending on the
    AGN type. Confirmations of this model exist for present times, but it is less
    clear in the early Universe. Here, we use the morphology of giant Ly α nebulae
    around AGNs at redshift z ∼ 3 to probe AGN emission and therefore the validity
    of the AGN unification model at this redshift. We compare the spatial morphology
    of 19 nebulae previously found around type I AGNs with a new sample of four Ly α
    nebulae detected around type II AGNs. Using two independent techniques, we find
    that nebulae around type II AGNs are more asymmetric than around type I, at least
    at radial distances r > 30 physical kpc (pkpc) from the ionizing source. We conclude
    that the type I and type II AGNs in our sample show evidence of different surrounding
    ionizing geometries. This suggests that the classical AGN unification model is
    also valid for high-redshift sources. Finally, we discuss how the lack of asymmetry
    in the inner parts (r ≲ 30 pkpc) and the associated high values of the He II to
    Ly α ratios in these regions could indicate additional sources of (hard) ionizing
    radiation originating within or in proximity of the AGN host galaxies. This work
    demonstrates that the morphologies of giant Ly α nebulae can be used to understand
    and study the geometry of high-redshift AGNs on circumnuclear scales and it lays
    the foundation for future studies using much larger statistical samples.

  text: While low-luminosity galaxies dominate number counts at all redshifts, their
    contribution to cosmic reionization is poorly understood due to a lack of knowledge
    of their physical properties. We isolate a sample of 35 z ≈ 4–5 continuum-faint
    Lyman-α emitters from deep VLT/MUSE spectroscopy and directly measure their H α
    emission using stacked Spitzer/IRAC Ch. 1 photometry. Based on Hubble Space Telescope
    imaging, we determine that the average UV continuum magnitude is fainter than
    −16 (≈ 0.01 L⋆), implying a median Lyman-α equivalent width of 259 Å. By combining
    the H α measurement with the UV magnitude, we determine the ionizing photon production
    efficiency, ξion, a first for such faint galaxies. The measurement of log10 (ξion
    [Hz erg−1]) = 26.28 (⁠+0.28−0.40⁠) is in excess of literature measurements of
    both continuum- and emission line-selected samples, implying a more efficient
    production of ionizing photons in these lower luminosity, Lyman-α-selected systems.
    We conclude that this elevated efficiency can be explained by stellar populations
    with metallicities between 4 × 10−4 and 0.008, with light-weighted ages less than
    3 Myr.
