  bibo_abstract:
  - 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.@eng
