| 英文摘要 | A general analysis for the d-wave pairing in two components fermion system. Two physical conditions which can induce mismatched Fermi surfaces are considered: (i) Fixed chemical potential asymmetry delta mu and (ii) fixed fermion number asymmetry alpha. In case (i), the gapless quasiparticle excitation arises both in usual Bardeen-Cooper-Schrieffer (BCS) and Sarma state due to the angle-dependent pairing gap, and they should be distinguished by gap susceptibility kappa Delta rather than the constraint Delta < delta mu. Meanwhile, the d-wave pairing can hold larger chemical potential asymmetry delta mu than the s-wave pairing. In case (ii), we find the angle dependence of the d-wave pairing gap can enhance the superfluidity for large asymmetry at low temperature. |
