Electronic EPR-like experiments with superconductors

Original · EN

We discuss a few situations related to non separable correlations in multiterminal hybrid structures. We show that the existence of such correlations can modify the strength of the gap of the superconductor. We discuss linear combinations of non local Cooper pairs. We discuss a possible transport experiment intended to probe non separable correlations. The models are worked out at the heuristic level of effective single site Green's functions.
