CDW scenario for pseudogap in normal state of bilayer cuprates

Abstract

Using the model of the singlet-correlated band the temperature dependence of d-wave superconducting (SC) and charge density wave (CDW) gaps have been calculated. Temperature interval of SC and CDW coexistence strongly depends on the relation between superexchange and Coulomb parameters. At low temperature the superconductivity suppresses CDW. © 1999 Published by Elsevier Science B.V. All rights reserved.
