Quantum Phase Transitions in mixtures of two identical Bosonic Species

ORAL

Abstract

We investigate the phase diagram of a two-component bosonic systems in a square lattice by means of quantum Monte Carlo simulation. Depending on the interplay between inter- and intra-species interactions we show the existence of intersting quantum phases such as, among others a demixed superfluid, a demixed Mott insulator, supercounterflow.
