摘要

受最近发现 CeRh2As2 超导态中可能存在场介导的奇偶性开关（Khim et al 2021 Science373 1012）的启发，我们深入研究了强耦合拉什巴单层和双层超导态对内部参数和外加磁场的依赖性。我们在一个类似 t-J 的模型中，对低温下层间配对、自旋轨道耦合、掺杂率和外加磁场的作用及其相互影响进行了数值研究，揭示了复杂的相图和不同对称性超导态之间的转变。

Phase diagram of strongly-coupled Rashba systems

Motivated by the recent discovery of a possible field-mediated parity switch within the superconducting state of CeRh2As2 (Khim et al 2021 Science373 1012), we thoroughly investigate the dependence of the superconducting state of a strongly-coupled Rashba mono- and bilayer on internal parameters and an applied magnetic field. The role of interlayer pairing, spin orbit coupling, doping rate and applied magnetic field and their interplay was examined numerically at low temperature within a t-J-like model, uncovering complex phase diagrams and transitions between superconducting states with different symmetry.
