Query: Emergence of non-abelian magnetic monopoles in a quantum impurity
  problem   Recently it was shown that molecules rotating in superfluid helium can be
described in terms of the angulon quasiparticles (Phys. Rev. Lett. 118, 095301
(2017)). Here we demonstrate that in the experimentally realized regime the
angulon can be seen as a point charge on a 2-sphere interacting with a gauge
field of a non-abelian magnetic monopole. Unlike in several other settings, the
gauge fields of the angulon problem emerge in the real coordinate space, as
opposed to the momentum space or some effective parameter space. Furthermore,
we find a topological transition associated with making the monopole abelian,
which takes place in the vicinity of the previously reported angulon
instabilities. These results pave the way for studying topological phenomena in
experiments on molecules trapped in superfluid helium nanodroplets, as well as
on other realizations of orbital impurity problems.
