摘要：

We investigate the behavior of the superconducting transition temperature within a previously developed BCS Bose-Einstein crossover picture. This picture, based on a decoupling scheme of Kadanoff and Martin, further extended by Patton, can be used to derive a simple form for the superconducting transition temperature in the presence of a pseudogap. We extend previous work which addressed the case of s-wave pairing in jellium, to explore the solutions for T-c as a function of variable coupling in more physically relevant situations. We thereby ascertain the effects of reduced dimensionality, periodic lattices, and a d-wave pairing interaction. Implications for the cuprate superconductors are discussed. [S0163-1829(99)01110-8].
