Abstract:
We study a hybrid normal-superconductor (NS) pi junction in which the nonlocal current can be orders of magnitude larger than that in earlier proposed systems. We calculate the electronic transport of this NS hybrid system when an external magnetic field is applied. It is shown that the nonlocal current exhibits oscillations as a function of the magnetic field, making the effect tunable with the field. The underlying classical dynamics is qualitatively discussed.
