摘要
Within the Hartree-Fock approximation (HFA) we calculate the London penetration depth A and the electromagnetic correlation length xi in the superconductor described by the Hubbard model with on-site attraction. We analyze the results as a function of electron density n and interaction, and discuss the differences in the n-dependence of lambda and T-C for the 2D SQ and 3D fee lattices.
