Abstract

We demonstrate that in the strong coupling limit (the superconducting gap Δ is as large as the chemical potential μ), which is relevant to the high-Tc superconductivity, the correlation corrections to the gap and critical temperature are about 10% of the corresponding mean field approximation values. For the weak coupling (Δ≪μ) the correlation corrections are very large: of the order of 100% of the corresponding mean field values. © 1996 The American Physical Society.
