Phases, instabilities and excitations in a two-component lattice model with photon-mediated interactions

Year: 2023

Type: article

Abstract: A comprehensive overview of the phase diagram, transitions, and low-energy excitations in a two-component spin Bose-Hubbard system with photon-mediated interactions is provided. The system features emergent antiferromagnetic ordered phases, stabilized by the interplay of short- and global-range interactions, and spin-exchange excitations with a tunable gap. It can be readily realized in cold-atom experiments with optical cavities.
