High-Tc Superconductivity via BCS and BEC Unification: A Review
Abstract
Description
Though commonly unrecognized, a superconducting BCS condensate consists of equal numbers of two-electron (2e) and two-hole (2h) Cooper pairs (CPs). A complete (in the sense that 2h-CPs are not ignored) boson-fermion statistical model, however, is able to depart from this perfect 2e-/2h-CP symmetry and yields robustly higher T_c's without abandoning electron-phonon dynamics. The complete model reduces to all the known statistical theories of superconductors, including the BCS-Bose "crossover" picture but going considerably beyond it.
