Transition temperature and a spatial dependence of the superconducting gap for multilayer high-temperature superconductors

Abstract

We derive the expressions for the transition temperature $(T_c)$, and the spatial dependence of the superconducting gap for a multilayer high-$T_c$ superconductor composed of groups of tightly spaced planes separated by a larger distance. The results are compared with experiment and provide a strong support for an interlayer hopping as the driving force of the large $T_c$ enhancement in multilayered compounds. Our results are universal in the sense that they are valid for an arbitrary pairing potential $V_{\mathbf{k}{\mathbf{k}}^{\prime }}$ in the $\mathrm{Cu}{\mathrm{O}}_2$ planes, as well as for both Fermi and nonFermi liquids.
