Stripe phase in the 1/8 doped 2D Hubbard model. 3. May 21, 2020 the doped Hubbard and t-J models. 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.

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. 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. t-J model was performed in [14] which con rmed the results of the previous studies in MFA [13].

The kinetic correlation operator exp(−λK) plays an important role in the emergence of superconductivity in large-U region of the two-dimensional Hubbard model, where U is the on-site Coulomb of superconductivity (SC) in the cuprates in terms of the two-dimensional (2D) Hubbard model [1,2]. It is believed that the three-band Hubbard model with d and p orbitals in the CuO. 2. plane (called the d-p model) captures the physics of high temperature superconductivity.
