Pair-density wave states through spin-orbit coupling in multilayer superconductors
Spin-singlet superconductors with quasi-two-dimensional multilayer structure are studied in high magnetic fields. Specifically, we concentrate on bi- and trilayer systems whose layers by symmetry are subject to Rashba-type spin-orbit coupling. The combination of magnetic field and spin-orbit coupling leads to a first-order phase transition between different states of layer-dependent superconducting …
