  text: We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation
    energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams,
    we sample the Møller-Plesset (MPn) perturbation series, obtaining accurate correlation
    energies up to n=5, with quadratic scaling in the number of basis functions. Our
    technique reduces the computational complexity of the molecular many-fermion correlation
    problem, opening up the possibility of low-scaling, accurate stochastic computations
    for a wide class of many-body systems described by Hugenholtz diagrams.

  text: We study an impurity with a resonance level whose position coincides with
    the Fermi energy of the surrounding Fermi gas. An impurity causes a rapid variation
    of the scattering phase shift for fermions at the Fermi surface, introducing a
    new characteristic length scale into the problem. We investigate manifestations
    of this length scale in the self-energy of the impurity and in the density of
    the bath. Our calculations reveal a model-independent deformation of the density
    of the Fermi gas, which is determined by the width of the resonance. To provide
    a broader picture, we investigate time evolution of the density in quench dynamics,
    and study the behavior of the system at finite temperatures. Finally, we briefly
    discuss implications of our findings for the Fermi-polaron problem.

  text: We combine experimental and theoretical approaches to explore excited rotational
    states of molecules embedded in helium nanodroplets using CS2 and I2 as examples.
    Laser-induced nonadiabatic molecular alignment is employed to measure spectral
    lines for rotational states extending beyond those initially populated at the
    0.37 K droplet temperature. We construct a simple quantum-mechanical model, based
    on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational
    energy structure in its entirety. The calculated and measured spectral lines are
    in good agreement. We show that the effect of the surrounding superfluid on molecular
    rotation can be rationalized by a single quantity, the angular momentum, transferred
    from the molecule to the droplet.

  text: We study a mobile quantum impurity, possessing internal rotational degrees
    of freedom, confined to a ring in the presence of a many-particle bosonic bath.
    By considering the recently introduced rotating polaron problem, we define the
    Hamiltonian and examine the energy spectrum. The weak-coupling regime is studied
    by means of a variational ansatz in the truncated Fock space. The corresponding
    spectrum indicates that there emerges a coupling between the internal and orbital
    angular momenta of the impurity as a consequence of the phonon exchange. We interpret
    the coupling as a phonon-mediated spin-orbit coupling and quantify it by using
    a correlation function between the internal and the orbital angular momentum operators.
    The strong-coupling regime is investigated within the Pekar approach, and it is
    shown that the correlation function of the ground state shows a kink at a critical
    coupling, that is explained by a sharp transition from the noninteracting state
    to the states that exhibit strong interaction with the surroundings. The results
    might find applications in such fields as spintronics or topological insulators
    where spin-orbit coupling is of crucial importance.

  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.

  text: "Alignment of OCS, CS2, and I2 molecules embedded in helium nanodroplets is
    measured as a function\r\nof time following rotational excitation by a nonresonant,
    comparatively weak ps laser pulse. The distinct\r\npeaks in the power spectra,
    obtained by Fourier analysis, are used to determine the rotational, B, and\r\ncentrifugal
    distortion, D, constants. For OCS, B and D match the values known from IR spectroscopy.
    For\r\nCS2 and I2, they are the first experimental results reported. The alignment
    dynamics calculated from the\r\ngas-phase rotational Schrödinger equation, using
    the experimental in-droplet B and D values, agree in\r\ndetail with the measurement
    for all three molecules. The rotational spectroscopy technique for molecules in\r\nhelium
    droplets introduced here should apply to a range of molecules and complexes."

  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: Dipolar (or spatially indirect) excitons (IXs) in semiconductor double quantum
    well (DQW) subjected to an electric field are neutral species with a dipole moment
    oriented perpendicular to the DQW plane. Here, we theoretically study interactions
    between IXs in stacked DQW bilayers, where the dipolar coupling can be either
    attractive or repulsive depending on the relative positions of the particles.
    By using microscopic band structure calculations to determine the electronic states
    forming the excitons, we show that the attractive dipolar interaction between
    stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW
    interaction energy and making the IX even more electrically polarizable. Many-particle
    interaction effects are addressed by considering the coupling between a single
    IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either
    as a closed-packed lattice or as a continuum IX fluid. We find that the lattice
    model yields IX interlayer binding energies decreasing with increasing lattice
    density. This behavior is due to the dominating role of the intra-DQW dipolar
    repulsion, which prevents more than one exciton from entering the attractive region
    of the inter-DQW coupling. Finally, both models shows that the single IX distorts
    the distribution of IXs in the adjacent DQW, thus inducing the formation of an
    IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with
    IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous
    dependence on density in semiquantitative agreement with a recent experimental
    study [cf. Hubert et al., Phys. Rev. X 9, 021026 (2019)].

  text: Nature creates electrons with two values of the spin projection quantum number.
    In certain applications, it is important to filter electrons with one spin projection
    from the rest. Such filtering is not trivial, since spin-dependent interactions
    are often weak, and cannot lead to any substantial effect. Here we propose an
    efficient spin filter based upon scattering from a two-dimensional crystal, which
    is made of aligned point magnets. The polarization of the outgoing electron flux
    is controlled by the crystal, and reaches maximum at specific values of the parameters.
    In our scheme, polarization increase is accompanied by higher reflectivity of
    the crystal. High transmission is feasible in scattering from a quantum cavity
    made of two crystals. Our findings can be used for studies of low-energy spin-dependent
    scattering from two-dimensional ordered structures made of magnetic atoms or aligned
    chiral molecules.

  text: "The oft-quoted dictum by Arthur Schawlow: ``A diatomic molecule has one atom
    too many'' has been disavowed. Inspired by the possibility to experimentally manipulate
    and enhance chemical reactivity in helium nanodroplets, we investigate the rotation
    of coupled cold molecules in the presence of a many-body environment.\r\nIn this
    thesis, we introduce new variational approaches to quantum impurities and apply
    them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other
    point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed
    out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox,
    we reveal the self-localization transition for the angulon quasiparticle. We show
    that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath
    coupling already at the mean-field level. The transition is accompanied by the
    spherical-symmetry breaking of the angulon ground state and a discontinuity in
    the first derivative of the ground-state energy. Moreover, the type of symmetry
    breaking is dictated by the symmetry of the microscopic impurity-bath interaction,
    which leads to a number of distinct self-localized states. \r\nFor the system
    containing multiple impurities, 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 from the strong-coupling regime to the weak
    molecule-bath interaction regime. We show that the molecules tend to have a strong
    alignment in the ground state, the biangulon shows shifted angulon instabilities
    and an additional spectral instability, where resonant angular momentum transfer
    between the molecules and the bath takes place. Finally, 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: Dipolar coupling plays a fundamental role in the interaction between electrically
    or magnetically polarized species such as magnetic atoms and dipolar molecules
    in a gas or dipolar excitons in the solid state. Unlike Coulomb or contactlike
    interactions found in many atomic, molecular, and condensed-matter systems, this
    interaction is long-ranged and highly anisotropic, as it changes from repulsive
    to attractive depending on the relative positions and orientation of the dipoles.
    Because of this unique property, many exotic, symmetry-breaking collective states
    have been recently predicted for cold dipolar gases, but only a few have been
    experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates.
    Here, we report on the first observation of attractive dipolar coupling between
    excitonic dipoles using a new design of stacked semiconductor bilayers. We show
    that the presence of a dipolar exciton fluid in one bilayer modifies the spatial
    distribution and increases the binding energy of excitonic dipoles in a vertically
    remote layer. The binding energy changes are explained using a many-body polaron
    model describing the deformation of the exciton cloud due to its interaction with
    a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud
    density indicates the important role of dipolar correlations, which is unique
    to dense, strongly interacting dipolar solid-state systems. Our concept provides
    a route for the realization of dipolar lattices with strong anisotropic interactions
    in semiconductor systems, which open the way for the observation of theoretically
    predicted new and exotic collective phases, as well as for engineering and sensing
    their collective excitations.

  text: The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
    space, is ideally suited for quantum control. Molecular angular momentum is naturally
    quantized, time evolution is governed by a well-known Hamiltonian with only a
    few accurately known parameters, and transitions between rotational levels can
    be driven by external fields from various parts of the electromagnetic spectrum.
    Control over the rotational motion can be exerted in one-, two-, and many-body
    scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity
    of bimolecular reactions, or encode quantum information to name just a few examples.
    The corresponding approaches to quantum control are pursued within separate, and
    typically disjoint, subfields of physics, including ultrafast science, cold collisions,
    ultracold gases, quantum information science, and condensed-matter physics. It
    is the purpose of this review to present the various control phenomena, which
    all rely on the same underlying physics, within a unified framework. To this end,
    recall the Hamiltonian for free rotations, assuming the rigid rotor approximation
    to be valid, and summarize the different ways for a rotor to interact with external
    electromagnetic fields. These interactions can be exploited for control—from achieving
    alignment, orientation, or laser cooling in a one-body framework, steering bimolecular
    collisions, or realizing a quantum computer or quantum simulator in the many-body
    setting.

  text: Problems involving quantum impurities, in which one or a few particles are
    interacting with a macroscopic environment, represent a pervasive paradigm, spanning
    across atomic, molecular, and condensed-matter physics. In this paper we introduce
    new variational approaches to quantum impurities and apply them to the Fröhlich
    polaron–a quasiparticle formed out of an electron (or other point-like impurity)
    in a polar medium, and to the angulon–a quasiparticle formed out of a rotating
    molecule in a bosonic bath. We benchmark these approaches against established
    theories, evaluating their accuracy as a function of the impurity-bath coupling.

  text: In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization
    of a magnetic material results in mechanical rotation and vice versa. At the microscopic
    level, this effect governs the transfer between electron spin and orbital angular
    momentum, and lattice degrees of freedom, understanding which is key for molecular
    magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now,
    the timescales of electron-to-lattice angular momentum transfer remain unclear,
    since modeling this process on a microscopic level requires the addition of an
    infinite amount of quantum angular momenta. We show that this problem can be solved
    by reformulating it in terms of the recently discovered angulon quasiparticles,
    which results in a rotationally invariant quantum many-body theory. In particular,
    we demonstrate that nonperturbative effects take place even if the electron-phonon
    coupling is weak and give rise to angular momentum transfer on femtosecond timescales.

  text: We demonstrate that identical impurities immersed in a two-dimensional many-particle
    bath can be viewed as flux-tube-charged-particle composites described by fractional
    statistics. In particular, we find that the bath manifests itself as an external
    magnetic flux tube with respect to the impurities, and hence the time-reversal
    symmetry is broken for the effective Hamiltonian describing the impurities. The
    emerging flux tube acts as a statistical gauge field after a certain critical
    coupling. This critical coupling corresponds to the intersection point between
    the quasiparticle state and the phonon wing, where the angular momentum is transferred
    from the impurity to the bath. This amounts to a novel configuration with emerging
    anyons. The proposed setup paves the way to realizing anyons using electrons interacting
    with superfluid helium or lattice phonons, as well as using atomic impurities
    in ultracold gases.

  text: We present an approach to interacting quantum many-body systems based on the
    notion of quantum groups, also known as q-deformed Lie algebras. In particular,
    we show that, if the symmetry of a free quantum particle corresponds to a Lie
    group G, in the presence of a many-body environment this particle can be described
    by a deformed group, Gq. Crucially, the single deformation parameter, q, contains
    all the information about the many-particle interactions in the system. We exemplify
    our approach by considering a quantum rotor interacting with a bath of bosons,
    and demonstrate that extracting the value of q from closed-form solutions in the
    perturbative regime allows one to predict the behavior of the system for arbitrary
    values of the impurity-bath coupling strength, in good agreement with nonperturbative
    calculations. Furthermore, the value of the deformation parameter allows one to
    predict at which coupling strengths rotor-bath interactions result in a formation
    of a stable quasiparticle. The approach based on quantum groups does not only
    allow for a drastic simplification of impurity problems, but also provides valuable
    insights into hidden symmetries of interacting many-particle systems.

  text: We introduce a diagrammatic Monte Carlo approach to angular momentum properties
    of quantum many-particle systems possessing a macroscopic number of degrees of
    freedom. The treatment is based on a diagrammatic expansion that merges the usual
    Feynman diagrams with the angular momentum diagrams known from atomic and nuclear
    structure theory, thereby incorporating the non-Abelian algebra inherent to quantum
    rotations. Our approach is applicable at arbitrary coupling, is free of systematic
    errors and of finite-size effects, and naturally provides access to the impurity
    Green function. We exemplify the technique by obtaining an all-coupling solution
    of the angulon model; however, the method is quite general and can be applied
    to a broad variety of systems in which particles exchange quantum angular momentum
    with their many-body environment.

  text: Recently it was shown that a molecule rotating in a quantum solvent can be
    described in terms of the “angulon” quasiparticle [M. Lemeshko, Phys. Rev. Lett.
    118, 095301 (2017)]. Here we extend the angulon theory to the case of molecules
    possessing an additional spin-1/2 degree of freedom and study the behavior of
    the system in the presence of a static magnetic field. We show that exchange of
    angular momentum between the molecule and the solvent can be altered by the field,
    even though the solvent itself is non-magnetic. In particular, we demonstrate
    a possibility to control resonant emission of phonons with a given angular momentum
    using a magnetic field.

  text: 'Rotation of molecules embedded in He nanodroplets is explored by a combination
    of fs laser-induced alignment experiments and angulon quasiparticle theory. We
    demonstrate that at low fluence of the fs alignment pulse, the molecule and its
    solvation shell can be set into coherent collective rotation lasting long enough
    to form revivals. With increasing fluence, however, the revivals disappear --
    instead, rotational dynamics as rapid as for an isolated molecule is observed
    during the first few picoseconds. Classical calculations trace this phenomenon
    to transient decoupling of the molecule from its He shell. Our results open novel
    opportunities for studying non-equilibrium solute-solvent dynamics and quantum
    thermalization. '
