Summary. We discuss concisely how the conventional Hubbard model and its generalizations (including phonons) might be good candidates for an explanation of high T c superconductivity, reviewing its properties both on crystals defined by conventional point groups and on non-Euclidean lattices. May 8, 2020 We introduce a variational state for one-dimensional two-orbital Hubbard models that intuitively explains the recent computational discovery of Sep 26, 2019 The Hubbard model, used to understand electron behavior in numerous quantum materials, now shows us its stripes, and superconductivity too Well, in my opinion, many other models for high temperature superconductivity are ineffective High-Tc superconductors are examples of strongly correlated („superconducting order“). „complexification“ of Hubbard model t'=0: no next- nearest neighbor hopping t' non-zero ultracold atom experiments cannot do t′ ≠ 0 Hubbard Model and Anyon Superconductivity (Lecture Notes in Physics) [ Balachandran, Aiyalam P, Ercolessi, Elisa, Srivastava, A M, Morandi, Giuseppe] on Superconducting correlation of the Hubbard model on a square lattice is reinvestigated by quantum Monte Carlo method. Results from more than one order of M. Miyazaki, K. Yamaji, T. YanagisawaEffects of higher hopping terms on the stripe states in the two-dimensional Hubbard model.

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. 2013-05-22 Hubbard model is not superconducting. The on-site repul-sion clearly is detrimental to on-site pairing, which can be discarded right away.

## 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.

### While scientists thought the Hubbard model, used for decades to represent electron behavior in numerous materials, might apply to cuprate high-temperature superconductors, until now they had no

The result is that the Hubbard model is a superconductor [5], but the symmetry of the pairing state is not d x2 2y. Rather, it is d xy at small t0=tand more exotic g wave at larger t0=t. Superconductivity in this limit is not caused by any pairing boson and originates from a pure Kohn-Luttinger e ect.

There is a subtle competition between stripe formation and superconductivity, which arise from the same Apr 15, 2011 The Hubbard model is to correlated electron systems as the Ising model is to statistical that superconductivity is impossible without attractive. May 30, 2019 Using cellular dynamical mean-field theory for the Hubbard model, we revisit the question of the coexistence and competition of these phases in 2019年9月27日 The Hubbard model is widely believed to contain the essential ingredients of high-temperature superconductivity.

In this paper a pairing mechanism caused by the kinematical interaction in the Hubbard model is considered. On the basis of equations of motion for two-time Green functions with anomalous pairings taken into account, equations are derived for the superconducting gap of an extended S-type and T{sub c}.
