The points of the Hubbard models. In these phase diagrams we will see a coexistence regime between the pure phases, called the hysteresis, where we can stabilize both metallic and insulating solutions. Our main question is, how does the phase diagram (and the hysteresis) look like if we vary the interaction terms. 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 … Phase diagram of the asymmetric Hubbard model Pavol Farkašovský Institute of Experimental Physics, Slovak Academy of Sciences, Watsonova 47, 040 01 Košice, Slovakia Received 27 November 2007; published 12 February 2008 The ground-state phase diagram of the asymmetric Hubbard model is studied in one and two dimensions by Ground-state phase diagram of the Hubbard model on a square lattice as a function of the ratio t/U and of the electron filling.

The Hubbard model, named after John Hubbard, is a simple model of interacting particles in a lattice, with only two terms in the Hamiltonian (see example below): a kinetic term allowing for tunneling ("hopping") of particles between sites of Quantum Phase Diagram of One-Dimensional Spin and Hubbard Models with Transitions to Bond Order Wave Phases† Manoranjan Kumar,a S.

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.

The effective lattice of the Wigner crystal is 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
