Nonsinusoidal current-phase relations in semiconductor-superconductor-ferromagnetic insulator devices
Andrea Maiani, Karsten Flensberg, Martin Leijnse +3
Coherent tunneling processes of multiple Cooper pairs across a Josephson junction give rise to higher harmonics in the current phase relation. In this work, we propose and study Jo…
