We derive a boundary condition for the Nambu Keldysh Green’s function in diffusive normal metal / unconventional superconductor junctions applicable for mixed parity pairing. Applying this theory to a 1d model of s + p -wave superconductor, we calculate LDOS in DN and charge conductance of DN / s + p -wave superconductor junctions. When the s -wave component of the pair potential is dominant, LDOS has a gap like structure at zero energy and the dominant pairing in DN is even-frequency spin…

Anisotropic differential conductance of a mixed parity superconductor/ferromagnet structure

We study the electronic transport properties of a superconductor (S) with a mixed s+p-wave pairing attached to a ferromagnetic metal (F) and a normal electrode (N) in an SFN configuration. Using the

Spin conductance in SNN junctions with non-centrosymmetric superconductors

An SNN-junction in which the superconducting potential is a mixture between s-wave and p-wave potentials is investigated using the Usadel equation equipped with Tanaka-Nazarov boundary conditions.

Odd-frequency pairs and anomalous proximity effect in nematic and chiral states of superconducting topological insulators

We investigate emergent odd-frequency pairs and proximity effect in nematic and chiral states of superconducting topological insulators (STIs), such as 𝑀 𝑥 Bi 2 Se 3 ( 𝑀 = Cu, Sr, Nb). The
