Parity Transition of Spin-Singlet Superconductivity Using Sublattice Degrees of Freedom
Parity Transition of Spin-Singlet Superconductivity Using Sublattice Degrees of Freedom
Recently, a superconducting (SC) transition from low-field (LF) to high-field (HF) SC states was reported in CeRh_{2}As_{2}, indicating the existence of multiple SC states. It has been theoretically noted that the existence of two Ce sites in the unit cell, the so-called sublattice degrees of freedom owing to the local …
