abstract: 'We identify the quantum phases in a binary mixture of dipolar bosons in 2D optical lattices. Our study is motivated by the recent experimental realization of binary dipolar condensate mixture of Er-Dy \[Phys. Rev. Lett. 121, 213601 (2018)\]. We model the system using the extended two-species Bose-Hubbard model and calculate the ground state phase diagrams using mean field theory. For selected cases we also obtain analytical phase boundaries using the site decoupled mean field theory. For comparison we also examine the phase diagram of two-species Bose-Hubbard model. Our results show that the quantum phases with the long range intra-species interaction phase separate with no phase ordering. The introduction of the long range inter-species interaction modifies the quantum phases of the system. It leads to the emergence of phase separated quantum phases with phase ordering. The transition from the phase separated quantum phases without phase ordering to phase ordered ones breaks the inversion symmetry.'
