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)PRLTAO0031-900710.1103/PhysRevLett.118.095301]. Here, we demonstrate that in the experimentally realized regime the angulon can be seen as a point charge on a two-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… Expand

Anyonic statistics of quantum impurities in two dimensions
We demonstrate that identical impurities immersed in a two-dimensional many-particle bath can be viewed as flux-tube-charged-particle composites described by fractional statistics. In particular, weExpand
Synthesis and observation of non-Abelian gauge fields in real space
Real-space building blocks for non-Abelian gauge fields, relevant for classical and quantum exotic topological phenomena, are introduced. Expand
Quantum Groups as Hidden Symmetries of Quantum Impurities.
The approach based on quantum groups does not only allow for a drastic simplification of impurity problems, but also provides valuable insights into hidden symmetries of interacting many-particle systems. Expand
Theory of the rotating polaron: Spectrum and self-localization
We study a quantum impurity possessing both translational and internal rotational degrees of freedom interacting with a bosonic bath. Such a system corresponds to a “rotating polaron,” which can beExpand
Magnetic monopoles with internal structure
We investigate the presence of magnetic monopoles in a model that extends the non Abelian model originally studied by 't Hooft and Polyakov with the inclusion of an extra neutral field. TheExpand

Bimagnetic Monopoles.
Motivated by recent results on small and hollow magnetic monopoles and on core and shell bimagnetic nanoparticles, we propose the construction of bimagnetic monopoles, which are structures thatExpand
Electromagnetic Asymmetry, Relegation of Curvature Singularities of Charged Black Holes, and Cosmological Equations of State in View of the Born--Infeld Theory
It is shown that, in a generic sense, and unlike what for electric point charges, the Born– Infeld nonlinear electrodynamics excludes monopoles as finite-energy magnetic point charges, thus spellingExpand
Intermolecular forces and correlations mediated by a phonon bath.
The biangulon quasiparticle is introduced, describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath, and a diagonalization scheme is introduced that allows the transition from two separated angulons to a biangULon as a function of the distance between the two molecules.

Synthetic spin-orbit coupling mediated by a bosonic environment
We study a mobile quantum impurity, possessing internal rotational degrees of freedom, confined to a ring in the presence of a many-particle bosonic bath. By considering the recently introducedExpand
