Abstract

Abstract The functional derivative δT c/δα 2(ω)F(ω) of the critical temperature (T c) with the electron-phonon spectral density (α 2(ω)F(ω)) gives information on the effectiveness of various phonon modes in enhancing T c. For an anisotropic superconductor, it is found that δT c/δα 2(ω)F(ω) goes negative at some small but finite phonon energy. This contrasts with the isotropic case for which it is well known that the functional derivative is positive everywhere. Thus, very low energy phonons reduce T c in an anisotropic superconductor which is similar to the known effects of static impurities that wash out anisotropy and hence reduce T c.
