Transverse thermoelectric conductivity and magnetization in high-[T.sub.c] superconductors

We use the time-dependent Ginzburg-Landau (TDGL) equation with thermal noise to calculate the transverse thermoelectric conductivity [α.sub.xy] describing the Nernst effect and magnetization [M.sub.z] in type-II superconductor in the vortex-liquid regime.

Description
Summary:We use the time-dependent Ginzburg-Landau (TDGL) equation with thermal noise to calculate the transverse thermoelectric conductivity [α.sub.xy] describing the Nernst effect and magnetization [M.sub.z] in type-II superconductor in the vortex-liquid regime. The nonlinear interaction term in dynamics is treated within self-consistent Gaussian approximation. The expressions of the transverse thermoelectric conductivity and magnetization including all the Landau levels are presented in explicit form which are applicable essentially to the whole phase. Our results are compared to recent simulation data on high-[T.sub.c] superconductor.
