Stable states for superconducting Systems with Combined S-Wave and D-wave Pairing. Zero Temperature Case

摘要

The Fermi-liquid system with S-wave and D-wave pairing interaction harmonics in considered. The general equations for energy gap and thermo- dynamic potential difference for arbitrary temperatures are given. The de- tailed calculations are performed for zero-temperature limit. The obtained results are illustrated and discussed. The value and structure of energy gap are presented. It is showed that the anisotropic gap can be realized only for g0 < g2.
