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 .

Our main results are the full phase diagrams for 2D t − t′ − U Hubbard model for t′ = 0 and t′ = −0.35t in Figs. 1 and 2, respectively. They were obtained for a system size so large that they are practically identical with the thermodynamic limit.

The In a recent study [Phys. Rev. X 10, 021042 (2020)], we showed using large-scale density matrix renormalization group (DMRG) simulations on infinite cylinders that the triangular lattice Hubbard model has a chiral spin liquid phase. In this work, we introduce hopping anisotropy in the model, making one of the three distinct bonds on the lattice stronger or weaker compared with the other two.

Our main question is, how does the phase diagram (and the hysteresis) look like if we vary the interaction terms. Phase diagram of the two-dimensional Hubbard-Holstein model Abstract. The electron–electron and electron–phonon interactions play an important role in correlated materials, being Introduction. The electron–phonon ( e-ph) interaction is a central issue in condensed matter, in particular when - The (t, ,U) phase diagram of the Bose-Hubbard model in one dimension (d = 1).
