Kinetic energy driven superconductivity in doped cuprates
Kinetic energy driven superconductivity in doped cuprates
Within the $t\ensuremath{-}J$ model, the mechanism of superconductivity in doped cuprates is studied based on the partial charge-spin separation fermion-spin theory. It is shown that dressed holons interact, occurring directly through the kinetic energy by exchanging dressed spinon excitations, leading to a net attractive force between dressed holons; then the …
