Nonequilibrium scenarios in cluster-forming quantum lattice models
Nonequilibrium scenarios in cluster-forming quantum lattice models
We investigate the out-of-equilibrium physics of monodisperse bosonic ensembles on a square lattice. The effective Hamiltonian description of these systems is given in terms of an extended Hubbard model with cluster-forming interactions relevant to experimental realizations with cold Rydberg-dressed atoms. The ground state of the model, recently investigated in [Phys. …
