Opening of pseudogaps due to superconducting critical fluctuations in quasi-two dimensions
Fusayoshi J. Ohkawa
We examine the role of the anisotropy of superconducting thermal critical fluctuations in the opening of pseudogaps in quasi-two dimensions. When the anisotropy of coherence or cor…

Application of Kondo-lattice theory to Mott-Hubbard metal-insulator crossover in disordered cuprate-oxide superconductors
Fusayoshi J. Ohkawa
A theory of Kondo lattices is applied to the crossover between local-moment magnetism and itinerant-electron magnetism in the t-J model on a quasi-two dimensional lattice. The Kond…

Electron-phonon interaction in cuprate-oxide superconductors
Fusayoshi J. Ohkawa
We propose a novel electron-phonon interaction arising from the modulation of the superexchange interaction by phonons. It is enhanced by spin and superconducting fluctuations, whi…
