Abstract

We simulate the experimental possibility of observing the antiferromagnetic (AF) order in the bosonic mixtures of rubidium $87$Rb and potassium $41$K in a two-dimensional optical lattice in the presence of harmonic confinement. By tuning the interspecies interactions and the lattice heights we have found the ground states, within the mean-field approximation, that interpolate from the phase separation to the AF order. For a moderate lattice height the coexistence of the Mott and AF phase is possible for the Rb atoms while the K atoms remain in the AF-superfluid phase. This observation may provide an experimental feasibility to hitherto unobserved AF order for 87Rb - 41K mixture.
