is studied theoretically. Use is made of the time-dependent Ginzburg-Landau (TDGL) equation due to Ebisawa and Fukuyama, which includes the correction term of the order ofT/μ as well, whereT is the temperature and μ is the chemical potential. It is shown that the thermoelectric power tends to zero as (T−T

Time variation of the Ginzburg--Landau order parameter
Elihu Abrahams,Toshihiko Tsuneto +1 more
TL;DR: In this paper, the authors use a nonequilibrium form of the Green's-function formulation of the BCS theory of superconductivity to investigate the circumstances under which differential equations in space and time, i.e., "time-dependent Ginzburg-Landau equations," give a valid description of the space-and time variation of the order parameter $\ensuremath{\Psi}$ in superconductors.
