Superconductivity 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.

Modeling high-temperature superconductivity (HTS) remains extremely challenging. Many 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.

Understanding high-temperature superconductivity in the cuprates [1] has been a long-standing mystery and one of the greatest challenges in theoretical condensed matter physics [2]. Very early on, the single-band two-dimensional (2D) Hubbard model [3], along with its cousin, the t-J … 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.

studies have been performed on this model to explain the superconductivity and/or the antiferro-magnetism of the copper oxides. A few work has been discussed the possibility of so called ﬂat band ferromagnetism in a type of d-p model[27]. In the present work, we address the multi-orbital Hubbard model in one-dimension and the d-p

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]. There are several later studies of superconductivity in the Hubbard model within the MFA [15{17], where, however, a spin-uctuation channel of superconducting pairing resulting from the anomalous component of the self-energy was not taken into account. 2013-09-02 · Technically, the Hubbard model is an extension of the so-called tight-binding model, wherein electrons can hop between lattice sites without 'feeling' each other. In its simplest form, electron Ferromagnetism and Superconductivity in Two-band Hubbard Models Kazuhiro Sano and Yoshiaki Ono¯ ⁄ (Department of Physics Engineering) (Received July 18, 2007) Abstract We investigate ferromagnetism and superconductivity in two types of two-band Hubbard mod-els: the multi-orbital Hubbard model and the d-p model, with particularly paying attention to 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 Understanding high-temperature superconductivity in copper oxide materials known as cuprates is one of the greatest challenges in theoretical condensed-matter physics. For more than 30 years, the leading mathematical model of this phenomenon has been the so-called 2D Hubbard model, a relatively simple model of particles interacting in a lattice. In particular, the hole superconductivity proposed by J. Hirsch [4], based on a generalized Hubbard model that includes nearest neighbor hopping (t) and the so-called nearestneighbor correlated 2013-05-22 · Recently developed numerical methods have enabled the explicit construction of the superconducting state of the Hubbard model of strongly correlated electrons in parameter regimes where the model also exhibits a pseudogap and a Mott insulating phase.

However, proving definitively that the model supports superconductivity is challenging.
