  bibo_abstract:
  - 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.@eng
