We present the global phase diagram of the extended boson Hubbard model on a simple cubic lattice by quantum Monte Carlo simulation with worm update algorithm. Four kinds of phases are supported by this model, including superfluid, supersolid, Mott, and charge density wave (CDW) states, which are identified in the phase diagram of chemical potential μ versus nearest neighbor interaction V .

We establish the phase diagram of the disordered three-dimensional Bose- Hubbard model at unity filling which has been controversial for many years.

We We theoretically study a generalized Hubbard model on Moir\\'e superlattices of twisted bilayers, and find very rich filling-factor-dependent quantum phase diagrams tuned by interaction strength and twist angle. Strong long-range Coulomb interaction in the Moir\\'e-Hubbard model induces Wigner crystals at a series of fractional filling factors.
