Description

We calculate the amplitude ratio C/sub +//C/sub -/ for specific-heat fluctuations near the superconducting-phase transition, taking into account the lowest-order fluctuations about mean-field theory. For a U(1) Ginzburg-Landau theory, minimally coupled to electromagnetism in d dimensions, C/sub +//C/sub -/ = 2/(2/sup d/2/+κ/sup -d/), where κ is the Ginzburg-Landau parameter. We discuss how this result arises from the microscopic theory of superconductivity
