A pairing hypothesis based on resonating valence bond state for hole
doped copper oxide high temperature superconductors    [PDF]

To explain the high-temperature superconductivity of hole-doped copper-oxide high-temperature superconductors (HDCO-HTSCs), Anderson proposed a theory: (A) the pseudogap state is a resonating valence-bond (RVB) state below T* and (B) the RVB state translates itself into high-temperature superconducting state below Tc. In this paper we abandon Anderson theory B but still retain Anderson theory A and add three new hypotheses. Jointed Anderson theory A with three hypotheses, we have brought pairing mechanism of HDCO-HTSCs into a framework of BCS theory and explained why Tc-line is a dome in phase diagram and why HDCO-HTSCs have a higher Tc_max than that of conventional superconductors.
