Proximity effect of time-reversal symmetry broken non-centrosymmetric superconductors
arXiv:2305.18918 · doi:10.1103/PhysRevB.108.094503
Abstract
In non-centrosymmetric superconductors the pair potential has both even-parity singlet and odd-parity triplet components. If time-reversal symmetry is broken, the superconducting phase of these components is not the same, for example in anapole superconductors. In this paper it is shown that breaking time-reversal symmetry by a phase difference between the two components significantly alters both the density of states and the conductance in s+helical p-wave superconductors. The density of states and conductance in s+chiral p-wave superconductors are less influenced by adding a phase difference because time reversal symmetry is already broken in the s+p-wave superconductor. The Tanaka-Nazarov boundary conditions are extended to 3D superconductors, allowing to investigate a greater variety of superconductors, such as B-W superconductors, in which the direction of the d-vector is parallel to the direction of momentum. The results are important for the determination of pair potentials in potentially time-reversal symmetry broken non-centrosymmetric superconductors.
