Supercurrent in the presence of direct transmission and a resonant localized state

Vukan Levajac, Hristo Barakov, Grzegorz P. Mazur +4

We study the current-phase relation (CPR) of an InSb-Al nanowire Josephson junction in parallel magnetic fields up to \,mT. At high magnetic fields and in narrow voltage inter…

Supercurrent parity-meter in a nanowire Cooper-pair transistor

Ji-Yin Wang, Constantin Schrade, Vukan Levajac +13

We study a Cooper-pair transistor realized by two Josephson weak links that enclose a superconducting island in an InSb-Al hybrid nanowire. When the nanowire is subject to a magnet…
