Transport properties calculation in the superconducting state for a quasi-two-dimensional system

Abstract

We performed a self-consistent calculation of the transport properties of a d-wave superconductor. We used for calculations the T-matrix approximation. The coresponding equations were evaluated numerically directly on the real frequecy axis. We studied the ab-plane charge dynamics in the coherent limit. For the c-axis charge dynamics, we considered both, the coherent and the incoherent limit. We also have calculated the penetration depth in this model.

Two dimensionality aspects of HTSC

“…These brief remarks are intended to indicate that how 2D character of cuprates is controversial and how difficult it is to take into account the layered structure of HTSC. Although, most HTSC models proposed have been built on a homogenous 2D electron system in the CuO 2 -layers of the cuprates [12], it remains to be examined whether the cuprates are 2D metals or 3D metals with strong anisotropy [13].…”
