  text: The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations
    of a many-body bath, can be used to describe an impurity rotating in a fluid or
    solid environment. Here, we propose a coherent state ansatz in the co-rotating
    frame, which provides a comprehensive theoretical description of angulons. We
    reveal the quasiparticle properties, such as energies, quasiparticle weights,
    and spectral functions, and show that our ansatz yields a persistent decrease
    in the impurity’s rotational constant due to many-body dressing, which is consistent
    with experimental observations. From our study, a picture of the angulon emerges
    as an effective spin interacting with a magnetic field that is self-consistently
    generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy,
    which focuses on the response of rotating molecules to a laser perturbation in
    the linear response regime. Importantly, we take into account initial-state interactions
    that have been neglected in prior studies and reveal their impact on the excitation
    spectrum. To examine the angulon instability regime, we use a single-excitation
    ansatz and obtain results consistent with experiments, in which a broadening of
    spectral lines is observed while phonon wings remain highly suppressed due to
    initial-state interactions.

  text: Studies on the experimental realization of two-dimensional anyons in terms
    of quasiparticles have been restricted, so far, to only anyons on the plane. It
    is known, however, that the geometry and topology of space can have significant
    effects on quantum statistics for particles moving on it. Here, we have undertaken
    the first step toward realizing the emerging fractional statistics for particles
    restricted to move on the sphere instead of on the plane. We show that such a
    model arises naturally in the context of quantum impurity problems. In particular,
    we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic
    or fermionic molecules immersed in a quantum many-particle environment can coincide
    with the anyonic spectrum on the sphere. This paves the way toward the experimental
    realization of anyons on the sphere using molecular impurities. Furthermore, since
    a change in the alignment of the molecules corresponds to the exchange of the
    particles on the sphere, such a realization reveals a novel type of exclusion
    principle for molecular impurities, which could also be of use as a powerful technique
    to measure the statistics parameter. Finally, our approach opens up a simple numerical
    route to investigate the spectra of many anyons on the sphere. Accordingly, we
    present the spectrum of two anyons on the sphere in the presence of a Dirac monopole
    field.

  text: Recently it was shown that anyons on the two-sphere naturally arise from a
    system of molecular impurities exchanging angular momentum with a many-particle
    bath (Phys. Rev. Lett. 126, 015301 (2021)). Here we further advance this approach
    and rigorously demonstrate that in the experimentally realized regime the lowest
    spectrum of two linear molecules immersed in superfluid helium corresponds to
    the spectrum of two anyons on the sphere. We develop the formalism within the
    framework of the recently experimentally observed angulon quasiparticle

  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: 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: One of the hallmarks of quantum statistics, tightly entwined with the concept
    of topological phases of matter, is the prediction of anyons. Although anyons
    are predicted to be realized in certain fractional quantum Hall systems, they
    have not yet been unambiguously detected in experiment. Here we introduce a simple
    quantum impurity model, where bosonic or fermionic impurities turn into anyons
    as a consequence of their interaction with the surrounding many-particle bath.
    A cloud of phonons dresses each impurity in such a way that it effectively attaches
    fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding
    quantum impurity model, first, provides a different approach to the numerical
    solution of the many-anyon problem, along with a concrete perspective of anyons
    as emergent quasiparticles built from composite bosons or fermions. More importantly,
    the model paves the way toward realizing anyons using impurities in crystal lattices
    as well as ultracold gases. In particular, we consider two heavy electrons interacting
    with a two-dimensional lattice crystal in a magnetic field, and show that when
    the impurity-bath system is rotated at the cyclotron frequency, impurities behave
    as anyons as a consequence of the angular momentum exchange between the impurities
    and the bath. A possible experimental realization is proposed by identifying the
    statistics parameter in terms of the mean-square distance of the impurities and
    the magnetization of the impurity-bath system, both of which are accessible to
    experiment. Another proposed application is impurities immersed in a two-dimensional
    weakly interacting Bose gas.

  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: 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 study a quantum impurity possessing both translational and internal rotational
    degrees of freedom interacting with a bosonic bath. Such a system corresponds
    to a “rotating polaron,” which can be used to model, e.g., a rotating molecule
    immersed in an ultracold Bose gas or superfluid helium. We derive the Hamiltonian
    of the rotating polaron and study its spectrum in the weak- and strong-coupling
    regimes using a combination of variational, diagrammatic, and mean-field approaches.
    We reveal how the coupling between linear and angular momenta affects stable quasiparticle
    states, and demonstrate that internal rotation leads to an enhanced self-localization
    in the translational degrees of freedom.

  text: 'Tunneling of a particle through a potential barrier remains one of the most
    remarkable quantum phenomena. Owing to advances in laser technology, electric
    fields comparable to those electrons experience in atoms are readily generated
    and open opportunities to dynamically investigate the process of electron tunneling
    through the potential barrier formed by the superposition of both laser and atomic
    fields. Attosecond-time and angstrom-space resolution of the strong laser-field
    technique allow to address fundamental questions related to tunneling, which are
    still open and debated: Which time is spent under the barrier and what momentum
    is picked up by the particle in the meantime? In this combined experimental and
    theoretical study we demonstrate that for strong-field ionization the leading
    quantum mechanical Wigner treatment for the time resolved description of tunneling
    is valid. We achieve a high sensitivity on the tunneling barrier and unambiguously
    isolate its effects by performing a differential study of two systems with almost
    identical tunneling geometry. Moreover, working with a low frequency laser, we
    essentially limit the non-adiabaticity of the process as a major source of uncertainty.
    The agreement between experiment and theory implies two substantial corrections
    with respect to the widely employed quasiclassical treatment: In addition to a
    non-vanishing longitudinal momentum along the laser field-direction we provide
    clear evidence for a non-zero tunneling time delay. This addresses also the fundamental
    question how the transition occurs from the tunnel barrier to free space classical
    evolution of the ejected electron.'

  text: Signatures of the Coulomb corrections in the photoelectron momentum distribution
    during laser-induced ionization of atoms or ions in tunneling and multiphoton
    regimes are investigated analytically in the case of a one-dimensional problem.
    A high-order Coulomb-corrected strong-field approximation is applied, where the
    exact continuum state in the S matrix is approximated by the eikonal Coulomb-Volkov
    state including the second-order corrections to the eikonal. Although without
    high-order corrections our theory coincides with the known analytical R-matrix
    (ARM) theory, we propose a simplified procedure for the matrix element derivation.
    Rather than matching the eikonal Coulomb-Volkov wave function with the bound state
    as in the ARM theory to remove the Coulomb singularity, we calculate the matrix
    element via the saddle-point integration method by time as well as by coordinate,
    and in this way avoiding the Coulomb singularity. The momentum shift in the photoelectron
    momentum distribution with respect to the ARM theory due to high-order corrections
    is analyzed for tunneling and multiphoton regimes. The relation of the quantum
    corrections to the tunneling delay time is discussed.

  text: 'It is a common knowledge that an effective interaction of a quantum impurity
    with an electromagnetic field can be screened by surrounding charge carriers,
    whether mobile or static. Here we demonstrate that very strong, "anomalous" screening
    can take place in the presence of a neutral, weakly polarizable environment, due
    to an exchange of orbital angular momentum between the impurity and the bath.
    Furthermore, we show that it is possible to generalize all phenomena related to
    isolated impurities in an external field to the case when a many-body environment
    is present, by casting the problem in terms of the angulon quasiparticle. As a
    result, the relevant observables such as the effective Rabi frequency, geometric
    phase, and impurity spatial alignment are straightforward to evaluate in terms
    of a single parameter: the angular-momentum-dependent screening factor.'

  text: The first hundred attoseconds of the electron dynamics during strong field
    tunneling ionization are investigated. We quantify theoretically how the electron’s
    classical trajectories in the continuum emerge from the tunneling process and
    test the results with those achieved in parallel from attoclock measurements.
    An especially high sensitivity on the tunneling barrier is accomplished here by
    comparing the momentum distributions of two atomic species of slightly deviating
    atomic potentials (argon and krypton) being ionized under absolutely identical
    conditions with near-infrared laser pulses (1300 nm). The agreement between experiment
    and theory provides clear evidence for a nonzero tunneling time delay and a nonvanishing
    longitudinal momentum of the electron at the “tunnel exit.”

  text: Recently it was shown that molecules rotating in superfluid helium can be
    described in terms of the angulon quasiparticles (Phys. Rev. Lett. 118, 095301
    (2017)). Here we demonstrate that in the experimentally realized regime the angulon
    can be seen as a point charge on a 2-sphere interacting with a gauge field of
    a non-abelian magnetic monopole. Unlike in several other settings, the gauge fields
    of the angulon problem emerge in the real coordinate space, as opposed to the
    momentum space or some effective parameter space. Furthermore, we find a topological
    transition associated with making the monopole abelian, which takes place in the
    vicinity of the previously reported angulon instabilities. These results pave
    the way for studying topological phenomena in experiments on molecules trapped
    in superfluid helium nanodroplets, as well as on other realizations of orbital
    impurity problems.
