Description
PT-symmetric structures have received particular interest due to their multiple applications in optics and synthetic materials. PT-symmetric superconductivity is a rather new, developing field. Here, I will show theoretically how such superconductor can be obtained due to spatiotemporal modulations of a material, that can lead to asymmetric electron-electron interaction. I will discuss Andreev bound states that appear in the junction with two conventional superconductors only at discrete values of phases of conventional superconductors. I will show, how Andreev scattering in a junction of PT-symmetric non-Hermitian superconductor with normal metal can be a check for validity of non-Hermitian formalism.
