Multiple Andreev reflections in hybrid multiterminal junctions

M. Houzet, P. Samuelsson

Published 2010-05-10Version 1

We investigate theoretically charge transport in hybrid multiterminal junctions with superconducting leads kept at different voltages. It is found that multiple Andreev reflections involving several superconducting leads give rise to rich subharmonic gap structures in the current-voltage characteristics. The structures are evidenced numerically in junctions in the incoherent regime.
