Phase transitions in dipolar gases in optical lattices
arXiv:1111.0550 · doi:10.1103/PhysRevA.85.025603
Abstract
We investigate the phase diagrams of two-dimensional lattice dipole systems with variable geometry. For bipartite square and triangular lattices with tunable vertical sublattice separation, we find rich phase diagrams featuring a sequence of easy-plane magnetically ordered phases separated by incommensurate spin-wave states.
