We show that for a half-filled band, the The Hubbard model has shown to be d-wave superconducting at weak interactions and in some specialized `plaquette’ calculations. We could recently show that the Hubbard model is also superconducting in the regime of intermediate interaction (~bandwidth), which is the regime relevant for the cuprates. This is a small python library to generate the basis and many-body Hamiltonian for the Fermi-Hubbard model. The Fermi-Hubbard model we are concerned with here is defined on some lattice is described by the Hamiltonian, Here the sum runs over the lattice indices and spin components (up and down), and the operator c i annihilates a particle on The Hubbard model was originally introduced to study itinerant ferromagnetism, based on the fact that this occurs in Hartree-Fock approximation so long as the “Stoner” criterion is satisfied, . However, more accurate numerical studies have found that ferromagnetism in the Hubbard model on a bipartite lattice with seems to require .

Exact solutions are possible for certain cases, for example when U=t= 0 or when = 1, the latter being the strong-coupling limit where doubly occupied sites are prohibited.

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.

We study a three-band model at particle density ρ = 2 / 3 , where the topological quantization of the 1D charge pump changes from Chern number C = 2 to C = − 1 as the interaction strength increases. Here we study a class of Hubbard models on decorated lattices, which have a special property that the corresponding single-electron Schrόdinger equation has 8 Apr 2020 For many-body physics, we construct a generalized Hubbard model on a triangular lattice based on the calculated single-particle moiré bands.
