text: In several settings of physics and chemistry one has to deal with molecules
interacting with some kind of an external environment, be it a gas, a solution,
or a crystal surface. Understanding molecular processes in the presence of such
a many-particle bath is inherently challenging, and usually requires large-scale
numerical computations. Here, we present an alternative approach to the problem,
based on the notion of the angulon quasiparticle. We show that molecules rotating
inside superfluid helium nanodroplets and Bose–Einstein condensates form angulons,
and therefore can be described by straightforward solutions of a simple microscopic
Hamiltonian. Casting the problem in the language of angulons allows us not only
to greatly simplify it, but also to gain insights into the origins of the observed
phenomena and to make predictions for future experimental studies.
