Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux
Commun. Phys. 6 224 (2023) The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding of a coupling between gauge potentials and matter. The typical formulation of the model is based upon a single particle picture, and should be extended when interactions with other particles...

| description | Commun. Phys. 6 224 (2023) The model of a ring threaded by the Aharonov-Bohm flux underlies our
understanding of a coupling between gauge potentials and matter. The typical
formulation of the model is based upon a single particle picture, and should be
extended when interactions with other particles become relevant. Here, we
illustrate such an extension for a particle in an Aharonov-Bohm ring subject to
interactions with a weakly interacting Bose gas. We show that the ground state
of the system can be described using the Bose polaron concept -- a particle
dressed by interactions with a bosonic environment. We connect the energy
spectrum to the effective mass of the polaron, and demonstrate how to change
currents in the system by tuning boson-particle interactions. Our results
suggest the Aharonov-Bohm ring as a platform for studying coherence and few- to
many-body crossover of quasi-particles that arise from an impurity immersed in
a medium. |
