Absztrakt:
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.
