Reentrant superconductivity in proximity to a topological insulator
arXiv:2012.01556 · doi:10.1103/PhysRevB.103.224508
Abstract
In the following paper we investigate the critical temperature behavior in the two-dimensional S/TI (S denotes superconductor and TI - topological insulator) junction with a proximity induced in-plane helical magnetization in the TI surface. The calculations of are performed using the general self-consistent approach based on the Usadel equations in Matsubara Green's functions technique. We show that the presence of the helical magnetization leads to the nonmonotonic behavior of the critical temperature as a function of the topological insulator layer thickness.
