@article{Yakaboylu2017EmergenceON, title={Emergence of Non-Abelian Magnetic Monopoles in a Quantum Impurity Problem.}, author={Enderalp Yakaboylu and Andreas Deuchert and Mikhail Lemeshko}, journal={Physical review letters}, year={2017}, volume={119 23}, pages={ 235301 } }

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…

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.
