Report

Superconductivity and Pseudogap in Quasi-Two-Dimensional Metals around the Antiferromagnetic Quantum Critical Point

Publikováno v: J. Phys. Soc. Jpn. 78, 013704 (2009)

Spin fluctuations (SF) and SF-mediated superconductivity (SC) in quasi-two-dimensional metals around the antiferrromagnetic (AF) quantum critical point (QCP) are investigated by using the self-consistent renormalization theory for SF and the strong c

Superconductivity in Organic Compounds with Pseudo-Triangular Lattice

Autor: Kondo, Hisashi, Moriya, Tôru

We study spin fluctuation (SF) mediated superconductivity (SC) in a half-filled square lattice Hubbard model with the transfer matrices -t between nearest neighbor sites and -t' between a half of next nearest neighbor sites neighboring along only one

Origin of Superconductivity in 2D-Organic Compounds and High-T_c Cuprates

Autor: Kondo, Hisashi, Moriya, Tôru

A phase diagram is drawn in a parameter space of the nearly half-filled single band two-dimensional Hubbard model with U/t, t'/t and n as the parameters, U, t, t' and n being the on-site interaction, the nearest and second nearest neighbor transfer m

Spin Fluctuation-Induced Superconductivity in \kappa-BEDT-TTF Compounds

Autor: Kondo, Hisashi, Moriya, Tôru

Spin fluctuation-induced superconductivity in quasi-two dimensional organic compounds, \kappa-BEDT-TTF salts, is investigated within a fluctuation exchange (FLEX) approximation using a half-filled Hubbard model with a right-angled isosceles triangula

Spin Fluctuation-Induced Superconductivity in Organic Compounds

Autor: Kondo, Hisashi, Moriya, Tôru

Spin fluctuation-induced superconductivity in two-dimensional organic compounds such as \kappa-(ET)_2-X is investigated by using a simplified dimer Hubbard model with right-angled isosceles triangular lattice (transfer matrices -\tau, -\tau^\prime).
