Conductance and current noise of a superconductor/ferromagnet quantum point contact
We study the conductance and current noise of a superconductor/ferromagnet $(S/F)$ single-channel quantum point contact (QPC) as a function of the QPC bias voltage using a scattering approach. We show that the spin dependence of interfacial phase shifts (SDIPS) acquired by electrons upon scattering by the QPC can strongly modify …
