Dec 7, 2018 The Fermi-Hubbard model, which is believed to explain the basis for high- temperature superconductivity, is extremely simple to describe, and

Several different models have recently been proposed to explain high temperature superconductivity. This is a review of two such proposals, namely the Hubbard and anyon models. There is a belief that they are actually interrelated and not mutually exclusive, although a convincing demonstration of any such connection is yet to be found.

Very early on, the single-band two-dimensional (2D) Hubbard model [3], along with its cousin, the t-J model, were argued to be the paradigmatic Mott transition, Hubbard model and superconductivity: an introduction A.-M. Tremblay G. Sordi, K. Haule, D. Sénéchal, P. Sémon, B. Kyung, G. Kotliar Trieste, 6 August, 2012 The superconducting instabilities of the doped repulsive 2D Hubbard model are studied in the inter-mediate to strong coupling regime with the help of the dynamical cluster approximation. To solve the effective cluster problem we employ an extended noncrossing approximation, which allows for a transi-tion to the broken symmetry state. 2019-10-20 · Abstract:We study the superconducting pairing correlations in the ground state of the doped Hubbard model -- in its original form without hopping beyond nearest neighbor or other perturbing parameters -- in two dimensions at intermediate to strong coupling and near optimal doping. The nature of such correlations has The Hubbard model is an approximate model used, especially in solid-state physics, to describe the transition between conducting and insulating systems. The Hubbard model, named after John Hubbard, is a simple model of interacting particles in a lattice, with only two terms in the Hamiltonian: a kinetic term allowing for tunneling of particles between sites of the lattice and a potential term consisting of an on-site interaction. The particles can either be fermions, as in Hubbard Superconductivity in the doped bilayer Hubbard model.

The single-band Hubbard model [26–28] is important since it can be regarded as a simpliﬁed model of the three-band d-p model and may contain important physics concerning high-temperature superconductivity [29–49]. The Hubbard model was ﬁrst proposed by Hubbard to describe the metal-insulator transition [50] and has
