摘要

This paper provides a theoretical analysis on the effects of an external Zeeman field and Rashba spin-orbit interactions on super-conductivity. We have extensively studied their influence on the superconducting transition temperature Tc and the quasiparticle excitation energy. Our investigation includes a detailed examination of both the s-wave and p-wave pairing states. Implications for the recently discovered family of superconductors, A2Cr3As3 (A = Na, K, Rb and Cs), as well as the validation of our theory have been discussed.
