Abstract

Motivated by the recent findings of unconventional superconductivity in CoSi2/TiSi2\mathrm{CoSi_2 / TiSi_2} heterostructures, we study the effect of interface induced Rashba spin orbit coupling on the conductance of a three terminal "T" shape superconducting device. We calculate the differential conductance for this device within the quasi-classical formalism that includes the mixing of triplet-singlet pairing due to the Rashba spin orbit coupling. We discuss our result in the light of the conductance spectra reported by Chiu {\it et al.} for CoSi2/TiSi2\mathrm{CoSi_2 / TiSi_2} heterostructures.
