Abstract

The time-dependent Ginzburg-Landau equation with thermal noise is used to calculate the Nernst signal eN, 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 Bi 2Sr 2CaCu 2O 8+δ and Bi 2Sr 2Ca 2Cu 3O 10+δ.
