First-principles calculations for underdoped La2−xSrxCuO4 (LSCO) have revealed a Fermi surface consisting of spin-triplet (KS) particles at the antinodal Fermi-pockets and spin-singlet (SS) particles at the nodal Fermi-arcs in the presence of AF lo

In 1986 Bednorz and Műller discovered high temperature superconductivity in copper oxides by chemically doping holes into La2CuO4 (LCO), the antiferromagnetic insulator. Despite intense experimental and theoretical research during the past 34 years,

By re-examination of Cabello, Estebaranz and Garcia-Alcaine's method (CEG) for constructing a ray set which gives a proof of Kochen–Specker theorem in a higher dimension from an already known set in a lower dimension, a more refined method is deriv

The present novel approach consists of two stages: in the first stage the many-electron states of a CuO6 octahedron or a CuO5 pyramid are calculated by the first-principles variational method, by taking into account the local distortions of a CuO6 oc

A brief review on the Kamimura–Suwa (K–S) model is first given. Then it is shown that an observed peculiar doping dependence of electronic entropy is explained by the K–S model successfully. Further it is shown on the basis of the K–S model t

A possibility of phonon-mediated interaction as a mechanism of high- T c superconductivity is discussed. Because of different spatial distribution of Bloch wave function for up-spin particle and down-spin particle in the present model, the effective

Firstly, a brief review is given on recent theoretical developments made by our group as to the many-body effect including electronic structure of hole-doped cuprates. Then the mechanism of superconductivity is discussed on the basis of the above-men

We have calculated the k, k′ dependence of the spectral function α 2 F(Σ, k, k′ ) using the renormalized one-electron-type band structure based on the extended two story house model by Kamimura and Suwa in which the states of carriers and local

Based on the model proposed by Kamimura and Suwa which bears important characteristics born from the interplay of Jahn–Teller Physics and Mott Physics, it is shown that the feature of Fermi surfaces is the Fermi pockets constructed by doped holes u
