  text: We study a linear rotor in a bosonic bath within the angulon formalism. Our
    focus is on systems where isotropic or anisotropic impurity-boson interactions
    support a shallow bound state. To study the fate of the angulon in the vicinity
    of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian.
    First, we use it to study attractive, spherically symmetric impurity-boson interactions
    for which the linear rotor can be mapped onto a static impurity. The well-known
    polaron formalism provides an adequate description in this limit. Second, we consider
    anisotropic potentials, and show that the presence of a shallow bound state with
    pronounced anisotropic character leads to a many-body instability that washes
    out the angulon dynamics.

  text: Coupling of orbital motion to a spin degree of freedom gives rise to various
    transport phenomena in quantum systems that are beyond the standard paradigms
    of classical physics. Here, we discuss features of spin-orbit dynamics that can
    be visualized using a classical model with two coupled angular degrees of freedom.
    Specifically, we demonstrate classical ‘spin’ filtering through our model and
    show that the interplay between angular degrees of freedom and dissipation can
    lead to asymmetric ‘spin’ transport.

  text: The development of two-dimensional materials has resulted in a diverse range
    of novel, high-quality compounds with increasing complexity. A key requirement
    for a comprehensive quantitative theory is the accurate determination of these
    materials' band structure parameters. However, this task is challenging due to
    the intricate band structures and the indirect nature of experimental probes.
    In this work, we introduce a general framework to derive band structure parameters
    from experimental data using deep neural networks. We applied our method to the
    penetration field capacitance measurement of trilayer graphene, an effective probe
    of its density of states. First, we demonstrate that a trained deep network gives
    accurate predictions for the penetration field capacitance as a function of tight-binding
    parameters. Next, we use the fast and accurate predictions from the trained network
    to automatically determine tight-binding parameters directly from experimental
    data, with extracted parameters being in a good agreement with values in the literature.
    We conclude by discussing potential applications of our method to other materials
    and experimental techniques beyond penetration field capacitance.

  text: We present a minimal model of ferroelectric large polarons, which are suggested
    as one of the mechanisms responsible for the unique charge transport properties
    of hybrid perovskites. We demonstrate that short-ranged charge–rotor interactions
    lead to long-range ferroelectric ordering of rotors, which strongly affects the
    carrier mobility. In the nonperturbative regime, where our theory cannot be reduced
    to any of the earlier models, we reveal that the polaron is characterized by large
    coherence length and a roughly tenfold increase of the effective mass as compared
    to the bare mass. These results are in good agreement with other theoretical predictions
    for ferroelectric polarons. Our model establishes a general phenomenological framework
    for ferroelectric polarons providing the starting point for future studies of
    their role in the transport properties of hybrid organic-inorganic perovskites.

  text: 'Traditionally, nuclear spin is not considered to affect biological processes.
    Recently, this has changed as isotopic fractionation that deviates from classical
    mass dependence was reported both in vitro and in vivo. In these cases, the isotopic
    effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects
    using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial
    dioxygen production system and biological aquaporin channels in cells. We observe
    that oxygen dynamics in chiral environments (in particular its transport) depend
    on nuclear spin, suggesting future applications for controlled isotope separation
    to be used, for instance, in NMR. To demonstrate the mechanism behind our findings,
    we formulate theoretical models based on a nuclear-spin-enhanced switch between
    electronic spin states. Accounting for the role of nuclear spin in biology can
    provide insights into the role of quantum effects in living systems and help inspire
    the development of future biotechnology solutions.'

  text: We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of
    a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared
    laser pulse. The time-dependent degree of alignment measured, exhibits a periodic,
    gradually decreasing structure that deviates qualitatively from that expected
    for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent
    rotational Schrödinger equation shows that the deviation is due to the alignment
    dependent interaction between the dimer and the droplet surface. This interaction
    confines the dimer to the tangential plane of the droplet surface at the point
    where it resides and is the reason that the observed alignment dynamics is also
    well described by a 2D quantum rotor model.

  text: The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding
    of a coupling between gauge potentials and matter. The typical formulation of
    the model is based upon a single particle picture, and should be extended when
    interactions with other particles become relevant. Here, we illustrate such an
    extension for a particle in an Aharonov-Bohm ring subject to interactions with
    a weakly interacting Bose gas. We show that the ground state of the system can
    be described using the Bose-polaron concept—a particle dressed by interactions
    with a bosonic environment. We connect the energy spectrum to the effective mass
    of the polaron, and demonstrate how to change currents in the system by tuning
    boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform
    for studying coherence and few- to many-body crossover of quasi-particles that
    arise from an impurity immersed in a medium.

  text: Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling
    (SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose
    and interpret quantum simulators of this problem in cold Bose gases. First, we
    derive a master equation that describes the model and explore it in a one-dimensional
    (1D) setting. To validate the standard assumptions needed for our derivation,
    we analyze available experimental data without SOC; as a byproduct, this analysis
    suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron
    approach at temperatures currently accessible in a cold-atom laboratory—motion
    of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate
    that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the
    information about SOC is incorporated in the initial conditions. Observables sensitive
    to this information (such as spin densities) can be used to study formation of
    steady spin polarization domains during quench dynamics.

  text: We show that the simplest of existing molecules—closed-shell diatomics not
    interacting with one another—host topological charges when driven by periodic
    far-off-resonant laser pulses. A periodically kicked molecular rotor can be mapped
    onto a “crystalline” lattice in angular momentum space. This allows us to define
    quasimomenta and the band structure in the Floquet representation, by analogy
    with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3
    of the molecular rotational period creates a lattice with three atoms per unit
    cell with staggered hopping. Within the synthetic dimension of the laser strength,
    we discover Dirac cones with topological charges. These Dirac cones, topologically
    protected by reflection and time-reversal symmetry, are reminiscent of (although
    not equivalent to) that seen in graphene. They—and the corresponding edge states—are
    broadly tunable by adjusting the laser strength and can be observed in present-day
    experiments by measuring molecular alignment and populations of rotational levels.
    This paves the way to study controllable topological physics in gas-phase experiments
    with small molecules as well as to classify dynamical molecular states by their
    topological invariants.

  text: Motivated by the recent discoveries of superconductivity in bilayer and trilayer
    graphene, we theoretically investigate superconductivity and other interaction-driven
    phases in multilayer graphene stacks. To this end, we study the density of states
    of multilayer graphene with up to four layers at the single-particle band structure
    level in the presence of a transverse electric field. Among the considered structures,
    tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density
    of states. We study the phases that can arise in ABCA graphene by tuning the carrier
    density and transverse electric field. For a broad region of the tuning parameters,
    the presence of strong Coulomb repulsion leads to a spontaneous spin and valley
    symmetry breaking via Stoner transitions. Using a model that incorporates the
    spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism
    for superconductivity driven by repulsive Coulomb interactions. We find that the
    strongest superconducting instability is in the p-wave channel, and occurs in
    proximity to the onset of Stoner transitions. Interestingly, we find a range of
    densities and transverse electric fields where superconductivity develops out
    of a strongly corrugated, singly connected Fermi surface in each valley, leading
    to a topologically nontrivial chiral p+ip superconducting state with an even number
    of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked
    tetralayer graphene as a promising platform for observing strongly correlated
    physics and topological superconductivity.

  text: Coherent control and manipulation of quantum degrees of freedom such as spins
    forms the basis of emerging quantum technologies. In this context, the robust
    valley degree of freedom and the associated valley pseudospin found in two-dimensional
    transition metal dichalcogenides is a highly attractive platform. Valley polarization
    and coherent superposition of valley states have been observed in these systems
    even up to room temperature. Control of valley coherence is an important building
    block for the implementation of valley qubit. Large magnetic fields or high-power
    lasers have been used in the past to demonstrate the control (initialization and
    rotation) of the valley coherent states. Here, the control of layer–valley coherence
    via strong coupling of valley excitons in bilayer WS2 to microcavity photons is
    demonstrated by exploiting the pseudomagnetic field arising in optical cavities
    owing to the transverse electric–transverse magnetic (TE–TM)mode splitting. The
    use of photonic structures to generate pseudomagnetic fields which can be used
    to manipulate exciton-polaritons presents an attractive approach to control optical
    responses without the need for large magnets or high-intensity optical pump powers.

  text: Superconductor-semiconductor hybrid devices are at the heart of several proposed
    approaches to quantum information processing, but their basic properties remain
    to be understood. We embed a twodimensional Al-InAs hybrid system in a resonant
    microwave circuit, probing the breakdown of superconductivity due to an applied
    magnetic field. We find a fingerprint from the two-component nature of the hybrid
    system, and quantitatively compare with a theory that includes the contribution
    of intraband p±ip pairing in the InAs, as well as the emergence of Bogoliubov-Fermi
    surfaces due to magnetic field. Separately resolving the Al and InAs contributions
    allows us to determine the carrier density and mobility in the InAs.

  text: Bernal-stacked multilayer graphene is a versatile platform to explore quantum
    transport phenomena and interaction physics due to its exceptional tunability
    via electrostatic gating. For instance, upon applying a perpendicular electric
    field, its band structure exhibits several off-center Dirac points (so-called
    Dirac gullies) in each valley. Here, the formation of Dirac gullies and the interaction-induced
    breakdown of gully coherence is explored via magnetotransport measurements in
    high-quality Bernal-stacked (ABA) trilayer graphene. At zero magnetic field, multiple
    Lifshitz transitions indicating the formation of Dirac gullies are identified.
    In the quantum Hall regime, the emergence of Dirac gullies is evident as an increase
    in Landau level degeneracy. When tuning both electric and magnetic fields, electron–electron
    interactions can be controllably enhanced until, beyond critical electric and
    magnetic fields, the gully degeneracy is eventually lifted. The arising correlated
    ground state is consistent with a previously predicted nematic phase that spontaneously
    breaks the rotational gully symmetry.

  text: We demonstrate the formation of robust zero-energy modes close to magnetic
    impurities in the iron-based superconductor FeSe1-z Tez. We find that the Zeeman
    field generated by the impurity favors a spin-triplet interorbital pairing as
    opposed to the spin-singlet intraorbital pairing prevalent in the bulk. The preferred
    spin-triplet pairing preserves time-reversal symmetry and is topological, as robust,
    topologically protected zero modes emerge at the boundary between regions with
    different pairing states. Moreover, the zero modes form Kramers doublets that
    are insensitive to the direction of the spin polarization or to the separation
    between impurities. We argue that our theoretical results are consistent with
    recent experimental measurements on FeSe1-z Tez.

  text: Ferromagnetism is most common in transition metal compounds but may also arise
    in low-density two-dimensional electron systems, with signatures observed in silicon,
    III-V semiconductor systems, and graphene moiré heterostructures. Here we show
    that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive
    the spontaneous ferromagnetic polarization of the electron system into one or
    more spin- and valley flavors. Using capacitance measurements on graphite-gated
    van der Waals heterostructures, we find a cascade of density- and electronic displacement
    field tuned phase transitions marked by negative electronic compressibility. The
    transitions define the boundaries between phases where quantum oscillations have
    either four-fold, two-fold, or one-fold degeneracy, associated with a spin and
    valley degenerate normal metal, spin-polarized `half-metal', and spin and valley
    polarized `quarter metal', respectively. For electron doping, the salient features
    are well captured by a phenomenological Stoner model with a valley-anisotropic
    Hund's coupling, likely arising from interactions at the lattice scale. For hole
    filling, we observe a richer phase diagram featuring a delicate interplay of broken
    symmetries and transitions in the Fermi surface topology. Finally, by rotational
    alignment of a hexagonal boron nitride substrate to induce a moiré superlattice,
    we find that the superlattice perturbs the preexisting isospin order only weakly,
    leaving the basic phase diagram intact while catalyzing the formation of topologically
    nontrivial gapped states whenever itinerant half- or quarter metal states occur
    at half- or quarter superlattice band filling. Our results show that rhombohedral
    trilayer graphene is an ideal platform for well-controlled tests of many-body
    theory and reveal magnetism in moiré materials to be fundamentally itinerant in
    nature.

  text: Superconductor-semiconductor hybrids are platforms for realizing effective
    p-wave superconductivity. Spin-orbit coupling, combined with the proximity effect,
    causes the two-dimensional semiconductor to inherit p±ip intraband pairing, and
    application of magnetic field can then result in transitions to the normal state,
    partial Bogoliubov Fermi surfaces, or topological phases with Majorana modes.
    Experimentally probing the hybrid superconductor-semiconductor interface is challenging
    due to the shunting effect of the conventional superconductor. Consequently, the
    nature of induced pairing remains an open question. Here, we use the circuit quantum
    electrodynamics architecture to probe induced superconductivity in a two dimensional
    Al-InAs hybrid system. We observe a strong suppression of superfluid density and
    enhanced dissipation driven by magnetic field, which cannot be accounted for by
    the depairing theory of an s-wave superconductor. These observations are explained
    by a picture of independent intraband p±ip superconductors giving way to partial
    Bogoliubov Fermi surfaces, and allow for the first characterization of key properties
    of the hybrid superconducting system.

  text: We show that in a two-dimensional electron gas with an annular Fermi surface,
    long-range Coulomb interactions can lead to unconventional superconductivity by
    the Kohn-Luttinger mechanism. Superconductivity is strongly enhanced when the
    inner and outer Fermi surfaces are close to each other. The most prevalent state
    has chiral p-wave symmetry, but d-wave and extended s-wave pairing are also possible.
    We discuss these results in the context of rhombohedral trilayer graphene, where
    superconductivity was recently discovered in regimes where the normal state has
    an annular Fermi surface. Using realistic parameters, our mechanism can account
    for the order of magnitude of Tc, as well as its trends as a function of electron
    density and perpendicular displacement field. Moreover, it naturally explains
    some of the outstanding puzzles in this material, that include the weak temperature
    dependence of the resistivity above Tc, and the proximity of spin singlet superconductivity
    to the ferromagnetic phase.

  text: The surface states of 3D topological insulators in general have negligible
    quantum oscillations (QOs) when the chemical potential is tuned to the Dirac points.
    In contrast, we find that topological Kondo insulators (TKIs) can support surface
    states with an arbitrarily large Fermi surface (FS) when the chemical potential
    is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency
    QOs, which can become comparable to the extremal area of the unhybridized bulk
    bands. We show that this occurs when the crystal symmetry is lowered from cubic
    to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow
    surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane
    hybridization leading to shadow surface states can be self-consistently stabilized
    for tetragonal TKIs. Consequently, shadow surface states provide an important
    example of high-frequency QOs beyond the context of cubic TKIs.

  text: We study an effective one-dimensional quantum model that includes friction
    and spin-orbit coupling (SOC), and show that the model exhibits spin polarization
    when both terms are finite. Most important, strong spin polarization can be observed
    even for moderate SOC, provided that the friction is strong. Our findings might
    help to explain the pronounced effect of chirality on spin distribution and transport
    in chiral molecules. In particular, our model implies static magnetic properties
    of a chiral molecule, which lead to Shiba-like states when a molecule is placed
    on a superconductor, in accordance with recent experimental data.

  text: Organic materials are known to feature long spin-diffusion times, originating
    in a generally small spin–orbit coupling observed in these systems. From that
    perspective, chiral molecules acting as efficient spin selectors pose a puzzle
    that attracted a lot of attention in recent years. Here, we revisit the physical
    origins of chiral-induced spin selectivity (CISS) and propose a simple analytic
    minimal model to describe it. The model treats a chiral molecule as an anisotropic
    wire with molecular dipole moments aligned arbitrarily with respect to the wire’s
    axes and is therefore quite general. Importantly, it shows that the helical structure
    of the molecule is not necessary to observe CISS and other chiral nonhelical molecules
    can also be considered as potential candidates for the CISS effect. We also show
    that the suggested simple model captures the main characteristics of CISS observed
    in the experiment, without the need for additional constraints employed in the
    previous studies. The results pave the way for understanding other related physical
    phenomena where the CISS effect plays an essential role.
