Spin-Triplet Superconductivity Mediated by Phonons in Quasi-One-Dimensional Systems
Yuuichi Suginishi, Hiroshi Shimahara
We investigate the spin-triplet superconductivity mediated by phonons in quasi-one-dimensional (Q1D) systems with open Fermi surfaces. We obtain the ground state phase diagrams. It…
Interlayer spin-singlet pairing induced by magnetic interactions in an antiferromagnetic superconductor
Hiroshi Shimahara
It is shown that interlayer spin-singlet Cooper pairing is induced by magnetic interactions in a metallic antiferromagnet of stacked conductive layers in which each layer is ferrom…
Reduction of Pauli paramagnetic pair-breaking effect in antiferromagnetic superconductors
Hiroshi Shimahara
Antiferromagnetic superconductors in a magnetic field are studied. We examine a mechanism which significantly reduces the Pauli paramagnetic pair-breaking effect. The mechanism is…
Effects of short-range correlations on the Coulomb screening and the pairing interactions in electron-phonon systems - triplet pairing mediated by phonons
Hiroshi Shimahara
Effects of short-range correlations on the Coulomb screening, the phonons, and the pairing interactions are examined in electron-phonon systems. First, we derive a model Hamiltonia…
Isotope effect in superconductors with coexisting interactions of phonon and nonphonon mechanisms
Hiroshi Shimahara
We examine the isotope effect of superconductivity in systems with coexisting interactions of phonon and nonphonon mechanisms in addition to the direct Coulomb interaction. The int…
Internal Transition of Superconducting State by Impurity Doping with a Jump of Isotope-effect Coefficient in Multiband Superconductors
Hiroshi Shimahara
The impurity effects on the transition temperature Tc and the isotope effect are examined in multiband superconductors with magnetic and nonmagnetic impurities, where the effect of…
