Wavepacket-current <--> supercurrent conversion in closed N/S/N circuits
Abstract
Description
The rise and decay in space and time of a supercurrent in a superconductor between two normal current leads connected to a reservoir is computed with the help of quasiparticle wavepackets which suffer Andreev scattering in the interfaces between the normal current leads and the superconductor. Stills from a computer movie visualize electron <-> hole scattering and the creation and destruction of the supercurrent.
