Abstract:
In this talk, we shall discuss on a minimal model to describe the quantum phases of ultracold polarized dipolar bosons in two-dimensional square optical lattice. The polarization axis of the dipoles can be canted with respect to the lattice plane by the external magnetic field. We study the quantum phases of the system arising from the variation in the tilt angle.Our study reveals that due to the anisotropic nature of the dipole-dipole
interaction, the system can undergo a structural phase transition between two quantum phases with different orders, checkerboard and striped. In addition, we shall discuss on the phase diagrams of the system illustrating the parameter regions of the quantum phases.
