Temperature effects on the calculation of the functional derivative of T(c) with respect to α(2)F(ω)

The functional derivative of the superconducting transition temperature T(c) with respect to the electron-phonon coupling function [Image: see text] permits identifying the frequency regions where phonons are most effective in raising T(c). This work presents an analysis of temperature effects on the calculation of the δT(c)/δα(2)F(ω) and μ* parameters. The results may permit establishing that the variation of the temperature in the δT(c)/δα(2)F(ω) and μ* parameter allows establishing patterns and conditions that are possibly related to the physical conditions in the superconducting state, with implications on the theoretical estimation of the T(c).
