- 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].

The phase diagram of the d = 3 Hubbard model is calculated as a function of temperature and electron density n i, in thefull range of densities between 0 and 2 electrons per site, using renormalization-group theory. An antiferromagnetic phase occurs at lower temperatures, at and near the half-ﬁlling density of n i = 1. Understanding phase diagrams of simple model systems precisely is about far more than testing well-established theory, and the 2D Fermi-Hubbard model is perhaps the best illustration of this point. A few decades after it was introduced, the model took on a new significance in the search for the cause of high-temperature superconductivity in copper-oxide compounds.

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. Regions of antiferromagnetic, d-wave superconducting, pseudo-gapped non-Fermi liquid, and Fermi liquid behaviors are found, in rough agreement with the generic phase diagram of the cuprates. The non-local fluctuations beyond the mean We study the mean-field phase diagram of the repulsive Hubbard model in the Lieb lattice.
