Effective interactions between rotating impurities immersed in a bosonic bath — •xiang li and mikhail lemeshko — IST, Klosterneuburg, Austria

As first reported in [1], an impurity exchanging angular momentum with the environment can be described as a new quasiparticle, the angulon. The outcome of the angulon theory has been shown to be in good agreement with experiments on molecules rotating in quantum solvents [2]. Here, we study the direct and bath -mediated interactions between two rotating molecular impurities in a bosonic bath. A theory of bi-angulon quasiparticle is proposed.
