  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.'
