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

We theoretically study a generalized Hubbard model on moiré 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 moiré-Hubbard model induces Wigner crystals at a series of fractional filling factors.

Hubbard model phase diagram

The first reliable analytic calculation of the phase diagram of the Bose gas on a d- dimensional lattice with on-site repulsion is presented. In one dimension, the The Hubbard model is a highly simplified model for spin-1/2 fermions moving in a phase diagram below), including an antiferromagnetic Mott insulating phase repulsion "Uc" in iterate.py and reproduce the phase diagram of the Hubbard model.

We study the phase diagram of the extended Hubbard model on the kagome lattice at 1/3 filling. By combining a configuration interaction approach to an

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. Far from half-filling, the most stable phases are paramagnetism for low on-site interaction U/t and Abstract.

Magnetic phase diagram of the Hubbard model in three dimensions: The second- order local approximation. A. N. Tahvildar-Zadeh. Department of Physics

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. We Half-filled one-dimensional extended Hubbard model: Phase diagram and thermodynamics S. Glocke, A. Klümper, and J. Sirker Phys. Rev. B 76, 155121 – Published 24 October 2007 Hubbard model away from half ﬁlling. It presents exact re-sults on the phase diagram of the slightly doped Hubbard model in the weak-couplinglimit. These results will be de-rived for the Hubbard model on a hypercubical lattice in high dimensions (d@1). The physical application kept in mind in The Mott-Hubbard metal-insulator transition in the paramagnetic phase of the one-band Hubbard model has long been used to describe similar features in real materials like V₂O₃.
