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 is considered. The general equations for energy gap and thermo-dynamic potential difference for arbitrary temperatures are given. The detailed 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 g_0 < g_2.
