Optical lattice with heterogeneous atomic density
arXiv:1502.01634 · doi:10.1088/1054-660X/25/3/035501
Abstract
The possibility is considered for the formation in optical lattices of a heterogeneous state characterized by a spontaneous mesoscopic separation of the system into the spatial regions with different atomic densities. It is shown that such states can arise, if there are repulsive interactions between atoms in different lattice sites and the filling factor is less than one-half.
