Quantum Phases of Soft-Core Dipolar Bosons in Optical Lattices — •Sebnem Günes Söyler1, Daniel Grimmer2, and Barbara Capogrosso-Sansone2 — 1Max Planck Institute for the Physics of Complex Systems, Dresden, Germany — 2University of Oklahoma, Norman, USA
We perform quantum Monte Carlo simulations of a system of soft-core ultracold bosonic atoms with dipolar interactions, confined in a two dimensional optical lattice. We consider long range isotropic repulsive interactions which refers to dipoles are alligned perpendicular to the plane. We calculate the ground state phase diagram for a parameter range that exhibits various solids, superfluid and supersolid phases. We also present finite temperature results and discuss the experimental feasibility of such phases.
