  bibo_abstract:
  - 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.@eng
