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 Bi(2)Sr(2)CaCu(2)O(8+delta) and Bi(2)Sr(2)Ca(2)Cu(3)O(10+delta). |
