Polinak, P. K. and Lambert, C. J. and Koltai, J. and Cserti, J. (2006) Andreev drag effect via magnetic quasiparticle focusing in normal-superconductor nanojunctions. Physical Review B: Condensed Matter and Materials Physics, 74 (13). p. 132508.Full text not available from this repository.
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.
