text: When a flat band is partially filled with electrons, strong Coulomb interactions
between them may lead to the emergence of topological gapped states with quantized
Hall conductivity. Such emergent topological states have been found in partially
filled Landau levels1 and Hofstadter bands2,3; however, in both cases, a large
magnetic field is required to produce the underlying flat band. The recent observation
of quantum anomalous Hall effects in narrow-band moiré materials4,5,6,7 has led
to the theoretical prediction that such phases could be realized at zero magnetic
field8,9,10,11,12. Here we report the observation of insulators with Chern number
C = 1 in the zero-magnetic-field limit at half-integer filling of the moiré superlattice
unit cell in twisted monolayer–bilayer graphene7,13,14,15. Chern insulators in
a half-filled band suggest the spontaneous doubling of the superlattice unit cell2,3,16,
and our calculations find a ground state of the topological charge density wave
at half-filling of the underlying band. The discovery of these topological phases
at fractional superlattice filling enables the further pursuit of zero-magnetic-field
phases that have fractional statistics that exist either as elementary excitations
or bound to lattice dislocations.

text: Glaciers in High Mountain Asia generate meltwater that supports the water
needs of 250 million people, but current knowledge of annual accumulation and
ablation is limited to sparse field measurements biased in location and glacier
size. Here, we present altitudinally-resolved specific mass balances (surface,
internal, and basal combined) for 5527 glaciers in High Mountain Asia for 2000–2016,
derived by correcting observed glacier thinning patterns for mass redistribution
due to ice flow. We find that 41% of glaciers accumulated mass over less than
20% of their area, and only 60% ± 10% of regional annual ablation was compensated
by accumulation. Even without 21st century warming, 21% ± 1% of ice volume will
be lost by 2100 due to current climatic-geometric imbalance, representing a reduction
in glacier ablation into rivers of 28% ± 1%. The ablation of glaciers in the Himalayas
and Tien Shan was mostly unsustainable and ice volume in these regions will reduce
by at least 30% by 2100. The most important and vulnerable glacier-fed river basins
(Amu Darya, Indus, Syr Darya, Tarim Interior) were supplied with >50% sustainable
glacier ablation but will see long-term reductions in ice mass and glacier meltwater
supply regardless of the Karakoram Anomaly.

text: The hippocampal mossy fiber synapse is a key synapse of the trisynaptic circuit.
Post-tetanic potentiation (PTP) is the most powerful form of plasticity at this
synaptic connection. It is widely believed that mossy fiber PTP is an entirely
presynaptic phenomenon, implying that PTP induction is input-specific, and requires
neither activity of multiple inputs nor stimulation of postsynaptic neurons. To
directly test cooperativity and associativity, we made paired recordings between
single mossy fiber terminals and postsynaptic CA3 pyramidal neurons in rat brain
slices. By stimulating non-overlapping mossy fiber inputs converging onto single
CA3 neurons, we confirm that PTP is input-specific and non-cooperative. Unexpectedly,
mossy fiber PTP exhibits anti-associative induction properties. EPSCs show only
minimal PTP after combined pre- and postsynaptic high-frequency stimulation with
intact postsynaptic Ca2+ signaling, but marked PTP in the absence of postsynaptic
spiking and after suppression of postsynaptic Ca2+ signaling (10 mM EGTA). PTP
is largely recovered by inhibitors of voltage-gated R- and L-type Ca2+ channels,
group II mGluRs, and vacuolar-type H+-ATPase, suggesting the involvement of retrograde
vesicular glutamate signaling. Transsynaptic regulation of PTP extends the repertoire
of synaptic computations, implementing a brake on mossy fiber detonation and a
“smart teacher” function of hippocampal mossy fiber synapses.

text: 'Extending on ideas of Lewin, Lieb, and Seiringer [Phys. Rev. B 100, 035127
(2019)], we present a modified “floating crystal” trial state for jellium (also
known as the classical homogeneous electron gas) with density equal to a characteristic
function. This allows us to show that three definitions of the jellium energy
coincide in dimensions d ≥ 2, thus extending the result of Cotar and Petrache
[“Equality of the Jellium and uniform electron gas next-order asymptotic terms
for Coulomb and Riesz potentials,” arXiv: 1707.07664 (2019)] and Lewin, Lieb,
and Seiringer [Phys. Rev. B 100, 035127 (2019)] that the three definitions coincide
in dimension d ≥ 3. We show that the jellium energy is also equivalent to a “renormalized
energy” studied in a series of papers by Serfaty and others, and thus, by the
work of Bétermin and Sandier [Constr. Approximation 47, 39–74 (2018)], we relate
the jellium energy to the order n term in the logarithmic energy of n points on
the unit 2-sphere. We improve upon known lower bounds for this renormalized energy.
Additionally, we derive formulas for the jellium energy of periodic configurations.'

text: There are two elementary superconducting qubit types that derive directly
from the quantum harmonic oscillator. In one, the inductor is replaced by a nonlinear
Josephson junction to realize the widely used charge qubits with a compact phase
variable and a discrete charge wave function. In the other, the junction is added
in parallel, which gives rise to an extended phase variable, continuous wave functions,
and a rich energy-level structure due to the loop topology. While the corresponding
rf superconducting quantum interference device Hamiltonian was introduced as a
quadratic quasi-one-dimensional potential approximation to describe the fluxonium
qubit implemented with long Josephson-junction arrays, in this work we implement
it directly using a linear superinductor formed by a single uninterrupted aluminum
wire. We present a large variety of qubits, all stemming from the same circuit
but with drastically different characteristic energy scales. This includes flux
and fluxonium qubits but also the recently introduced quasicharge qubit with strongly
enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.
The use of a geometric inductor results in high reproducibility of the inductive
energy as guaranteed by top-down lithography—a key ingredient for intrinsically
protected superconducting qubits.

text: In this article we introduce a complete gradient estimate for symmetric quantum
Markov semigroups on von Neumann algebras equipped with a normal faithful tracial
state, which implies semi-convexity of the entropy with respect to the recently
introduced noncommutative 2-Wasserstein distance. We show that this complete gradient
estimate is stable under tensor products and free products and establish its validity
for a number of examples. As an application we prove a complete modified logarithmic
Sobolev inequality with optimal constant for Poisson-type semigroups on free group
factors.

text: "The numerical simulation of dynamical phenomena in interacting quantum systems
is a notoriously hard problem. Although a number of promising numerical methods
exist, they often have limited applicability due to the growth of entanglement
or the presence of the so-called sign problem. In this work, we develop an importance
sampling scheme for the simulation of quantum spin dynamics, building on a recent
approach mapping quantum spin systems to classical stochastic processes. The importance
sampling scheme is based on identifying the classical trajectory that yields the
largest contribution to a given quantum observable. An exact transformation is
then carried out to preferentially sample trajectories that are close to the dominant
one. We demonstrate that this approach is capable of reducing the temporal growth
of fluctuations in the stochastic quantities, thus extending the range of accessible
times and system sizes compared to direct sampling. We discuss advantages and
limitations of the proposed approach, outlining directions\r\nfor further developments."

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: Practical quantum networks require low-loss and noise-resilient optical interconnects
as well as non-Gaussian resources for entanglement distillation and distributed
quantum computation. The latter could be provided by superconducting circuits
but existing solutions to interface the microwave and optical domains lack either
scalability or efficiency, and in most cases the conversion noise is not known.
In this work we utilize the unique opportunities of silicon photonics, cavity
optomechanics and superconducting circuits to demonstrate a fully integrated,
coherent transducer interfacing the microwave X and the telecom S bands with a
total (internal) bidirectional transduction efficiency of 1.2% (135%) at millikelvin
temperatures. The coupling relies solely on the radiation pressure interaction
mediated by the femtometer-scale motion of two silicon nanobeams reaching a Vπ
as low as 16 μV for sub-nanowatt pump powers. Without the associated optomechanical
gain, we achieve a total (internal) pure conversion efficiency of up to 0.019%
(1.6%), relevant for future noise-free operation on this qubit-compatible platform.

text: Aqueous iodine based electrochemical energy storage is considered a potential
candidate to improve sustainability and performance of current battery and supercapacitor
technology. It harnesses the redox activity of iodide, iodine, and polyiodide
species in the confined geometry of nanoporous carbon electrodes. However, current
descriptions of the electrochemical reaction mechanism to interconvert these species
are elusive. Here we show that electrochemical oxidation of iodide in nanoporous
carbons forms persistent solid iodine deposits. Confinement slows down dissolution
into triiodide and pentaiodide, responsible for otherwise significant self-discharge
via shuttling. The main tools for these insights are in situ Raman spectroscopy
and in situ small and wide-angle X-ray scattering (in situ SAXS/WAXS). In situ
Raman confirms the reversible formation of triiodide and pentaiodide. In situ
SAXS/WAXS indicates remarkable amounts of solid iodine deposited in the carbon
nanopores. Combined with stochastic modeling, in situ SAXS allows quantifying
the solid iodine volume fraction and visualizing the iodine structure on 3D lattice
models at the sub-nanometer scale. Based on the derived mechanism, we demonstrate
strategies for improved iodine pore filling capacity and prevention of self-discharge,
applicable to hybrid supercapacitors and batteries.

text: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. By analogy with the bipolaron, we introduce the biangulon quasiparticle
describing two rotating molecules that align with respect to each other due to
the effective attractive interaction mediated by the excitations of the bath.
We study this system in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, we introduce a diagonalization scheme that allows us to describe
the transition from two separated angulons to a biangulon as a function of the
distance between the two molecules.

text: Glioblastoma is the most malignant cancer in the brain and currently incurable.
It is urgent to identify effective targets for this lethal disease. Inhibition
of such targets should suppress the growth of cancer cells and, ideally also precancerous
cells for early prevention, but minimally affect their normal counterparts. Using
genetic mouse models with neural stem cells (NSCs) or oligodendrocyte precursor
cells (OPCs) as the cells‐of‐origin/mutation, it is shown that the susceptibility
of cells within the development hierarchy of glioma to the knockout of insulin‐like
growth factor I receptor (IGF1R) is determined not only by their oncogenic states,
but also by their cell identities/states. Knockout of IGF1R selectively disrupts
the growth of mutant and transformed, but not normal OPCs, or NSCs. The desirable
outcome of IGF1R knockout on cell growth requires the mutant cells to commit to
the OPC identity regardless of its development hierarchical status. At the molecular
level, oncogenic mutations reprogram the cellular network of OPCs and force them
to depend more on IGF1R for their growth. A new‐generation brain‐penetrable, orally
available IGF1R inhibitor harnessing tumor OPCs in the brain is also developed.
The findings reveal the cellular window of IGF1R targeting and establish IGF1R
as an effective target for the prevention and treatment of glioblastoma.

text: In laboratory studies and numerical simulations, we observe clear signatures
of unstable time-periodic solutions in a moderately turbulent quasi-two-dimensional
flow. We validate the dynamical relevance of such solutions by demonstrating that
turbulent flows in both experiment and numerics transiently display time-periodic
dynamics when they shadow unstable periodic orbits (UPOs). We show that UPOs we
computed are also statistically significant, with turbulent flows spending a sizable
fraction of the total time near these solutions. As a result, the average rates
of energy input and dissipation for the turbulent flow and frequently visited
UPOs differ only by a few percent.

text: Understanding the conformational sampling of translation-arrested ribosome
nascent chain complexes is key to understand co-translational folding. Up to now,
coupling of cysteine oxidation, disulfide bond formation and structure formation
in nascent chains has remained elusive. Here, we investigate the eye-lens protein
γB-crystallin in the ribosomal exit tunnel. Using mass spectrometry, theoretical
simulations, dynamic nuclear polarization-enhanced solid-state nuclear magnetic
resonance and cryo-electron microscopy, we show that thiol groups of cysteine
residues undergo S-glutathionylation and S-nitrosylation and form non-native disulfide
bonds. Thus, covalent modification chemistry occurs already prior to nascent chain
release as the ribosome exit tunnel provides sufficient space even for disulfide
bond formation which can guide protein folding.

text: The actin-related protein (Arp)2/3 complex nucleates branched actin filament
networks pivotal for cell migration, endocytosis and pathogen infection. Its activation
is tightly regulated and involves complex structural rearrangements and actin
filament binding, which are yet to be understood. Here, we report a 9.0 Å resolution
structure of the actin filament Arp2/3 complex branch junction in cells using
cryo-electron tomography and subtomogram averaging. This allows us to generate
an accurate model of the active Arp2/3 complex in the branch junction and its
interaction with actin filaments. Notably, our model reveals a previously undescribed
set of interactions of the Arp2/3 complex with the mother filament, significantly
different to the previous branch junction model. Our structure also indicates
a central role for the ArpC3 subunit in stabilizing the active conformation.

text: Confining molecules can fundamentally change their chemical and physical properties.
Confinement effects are considered instrumental at various stages of the origins
of life, and life continues to rely on layers of compartmentalization to maintain
an out-of-equilibrium state and efficiently synthesize complex biomolecules under
mild conditions. As interest in synthetic confined systems grows, we are realizing
that the principles governing reactivity under confinement are the same in abiological
systems as they are in nature. In this Review, we categorize the ways in which
nanoconfinement effects impact chemical reactivity in synthetic systems. Under
nanoconfinement, chemical properties can be modulated to increase reaction rates,
enhance selectivity and stabilize reactive species. Confinement effects also lead
to changes in physical properties. The fluorescence of light emitters, the colours
of dyes and electronic communication between electroactive species can all be
tuned under confinement. Within each of these categories, we elucidate design
principles and strategies that are widely applicable across a range of confined
systems, specifically highlighting examples of different nanocompartments that
influence reactivity in similar ways.

text: The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap
dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength
range. These observations have opened up the possibility of attosecond metrology
in solids, which would benefit from a precise measurement of the emission times
of individual harmonics with respect to the NIR laser field. Here we show that,
when high-harmonics are detected from the input surface of a magnesium oxide crystal,
a bichromatic probing of the XUV emission shows a clear synchronization largely
consistent with a semiclassical model of electron–hole recollisions in bulk solids.
On the other hand, the bichromatic spectrogram of harmonics originating from the
exit surface of the 200 μm-thick crystal is strongly modified, indicating the
influence of laser field distortions during propagation. Our tracking of sub-cycle
electron and hole re-collisions at XUV energies is relevant to the development
of solid-state sources of attosecond pulses.

text: Attosecond chronoscopy has revealed small but measurable delays in photoionization,
characterized by the ejection of an electron on absorption of a single photon.
Ionization-delay measurements in atomic targets provide a wealth of information
about the timing of the photoelectric effect, resonances, electron correlations
and transport. However, extending this approach to molecules presents challenges,
such as identifying the correct ionization channels and the effect of the anisotropic
molecular landscape on the measured delays. Here, we measure ionization delays
from ethyl iodide around a giant dipole resonance. By using the theoretical value
for the iodine atom as a reference, we disentangle the contribution from the functional
ethyl group, which is responsible for the characteristic chemical reactivity of
a molecule. We find a substantial additional delay caused by the presence of a
functional group, which encodes the effect of the molecular potential on the departing
electron. Such information is inaccessible to the conventional approach of measuring
photoionization cross-sections. The results establish ionization-delay measurements
as a valuable tool in investigating the electronic properties of molecules.

text: 'The fundamental and practical importance of particle stabilization has motivated
various characterization methods for studying polymer brushes on particle surfaces.
In this work, we show how one can perform sensitive measurements of neutral polymer
coating on colloidal particles using a commercial zetameter and salt solutions.
By systematically varying the Debye length, we study the mobility of the polymer-coated
particles in an applied electric field and show that the electrophoretic mobility
of polymer-coated particles normalized by the mobility of non-coated particles
is entirely controlled by the polymer brush and independent of the native surface
charge, here controlled with pH, or the surface–ion interaction. Our result is
rationalized with a simple hydrodynamic model, allowing for the estimation of
characteristics of the polymer coating: the brush length L, and the Brinkman length
ξ, determined by its resistance to flows. We demonstrate that the Debye layer
provides a convenient and faithful probe to the characterization of polymer coatings
on particles. Because the method simply relies on a conventional zetameter, it
is widely accessible and offers a practical tool to rapidly probe neutral polymer
brushes, an asset in the development and utilization of polymer-coated colloidal
particles.'
