摘要: The time-dependent Ginzburg Landau equation with thermal noise is used to calculate the Nernst signal e(N), describing the Nernst effect, in type-II superconductor in the vortex-liquid regime. The Gaussian method used is an elaboration of the Hartree-Fock method. An additional assumption often made in analytical calculations that only the lowest Landau level significantly contributes to physical quantities of interest in the high-field limit is lifted by including all the Landau levels. The values of eN are in good quantitative agreement with experimental data for temperature close to T-c on Bi2Sr2CaCu2O8+delta and Bi2Sr2Ca2Cu3O10+delta.
