Phase transitions in dipolar gases in optical lattices    [PDF]

Y. Sherkunov, Vadim V. Cheianov, Vladimir Fal'ko

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.
