Abstract:
Noncentrosymmetric superconductivity has attracted considerable attention in recent years [1]. While a superconductor lacks an inversion center in its crystal structure, the antisymmetric spin-orbital coupling (ASOC) may split the spin degeneracy of conduction electrons and allows the admixture of spin-singlet and spin-triplet pairing state, leading to rich physical properties. In this talk, I will overview the recent progress on the study of noncentrosymmetric superconductors, covering heavy fermions systems, weakly correlated systems with different spin-orbit coupling strength and the more recent work of superconductivity with broken time reversal symmetry.
