- The (t, p) phase diagram of the Bose-Hubbard model in two dimensions (d = 2). The solid lines give the phase boundaries of the Mott insulator to the superfluid state as determined from a third-order strong-coupling calculation. The point indicates the tricritical point as determined by the QMC calculation of Krauth and Trivedi [7].

Freericks 1,2 and H Explicit expressions for the energy of the Mott and the "defect" phase are given in a strong Ground state phase diagram of the Hubbard-Holstein model at the half-filling of the square lattice, and adiabaticity ratio ω0 / t = 1. The hatched region exhibits a correlated metallic (or We study the mean-field phase diagram of the repulsive Hubbard model in the Lieb lattice.

The phase diagram of the d = 3 Hubbard model is calculated as a function of temperature and electron density hn i i, in the full range of densities between 0 and 2 electrons per site, using renormalization-group theory.

Ōno and R. Bulla and A. Hewson}, journal={The European Physical Journal B - Condensed Matter and Complex Systems}, year={2001}, volume={19}, pages={375-384} } We examine the zero- and finite-temperature phase diagrams of soft-core bosons of the extended Bose-Hubbard model on a square optical lattice. To study various quantum phases and their transitions we employ single-site and cluster Gutzwiller mean-field theory. We have observed that the Mott insulator phase vanishes above a critical value of nearest-neighbor interaction and the supersolid phase Phase diagrams of the disordered Bose-Hubbard model with cavity-mediated long-range and nearest-neighbor interactions?

• Critical temperatures are determined in the T-matrix approach, across BCS–BEC crossover. • Temperature phase diagrams of AHM beyond mean field approximation are constructed. • The phase diagram in the μ / U vs z V / U plane for the extended Bose Hubbard model on a simple cubic lattice, where U = 40 t and the lattice size is 12 × 12 × 12. Four kinds of phases including the superfluid (SF), supersolid (SS), Mott, and CDW states are identified. The CDW states are further classified as I and II by the filling numbers.

Single-atom resolution imaging of the Bose–Hubbard model has been possible since 2009 using quantum gas microscopes. The Dynamical Cluster Approximation (DCA) is used to study non-local corrections to the dynamical mean field phase diagram of the two-dimensional Hubbard model.

The phase diagram of the attractive Hubbard model with spatially inhomogeneous interactions is obtained using a single-site dynamical mean-ﬁeld theory-like approach. The model is characterized by three parameters: the interaction strength, the active fraction fraction of sites with the attractive interaction , and electron ﬁlling.
