Abstract

The stripe phase in high Tc cuprates is modeled as a single stripe coupled to the resonating valence bond (RVB) spin liquid background by the single particle hopping process. In the normal state, the strong pairing correlation inherent in a RVB state is thus transferred into the Luttinger stripe and drives it toward spin-gap formation described by the Luther-Emery model. The establishment of global phase coherence in the superconducting state contributes to a more relevant coupling to Luther-Emery stripe and leads to gap opening in both spin and charge sectors. Physical consequences of the present picture are discussed.
