Wave equations of elastic type-II superconductors

It is shown that when the thermodynamic fluxes are included as independent thermodynamic state variables of the generalized entropy density, the const itutive equations for the conserved state variables and the evolution equat ions for the nonconserved state variables of elastic type-II superconductor s can be derived systematically. In particular, the transport equations gen eralizing the Fourier law for heat transport and the time-dependent Ginzbur g-Landau equation for the relaxation of superelectron are proposed in this paper.
