【 摘 要 】

Many-body localization (MBL) features are studied here for a large spin chain model with long-range interactions. The model corresponds to cold atoms placed inside a cavity and driven by an external laser field with long-range interactions coming from rescattering of cavity photons. Earlier studies were limited to small sizes amenable to exact diagonalization. It is shown that nonergodic features and MBL may exist in this model for random disorder as well as in the presence of tilted potential on experimental timescales also for experimentally relevant system sizes using tensor network algorithms.
