Description
Driving a Josephson junction with two dephased AC oscillating fields can pump a DC Josephson current and plays the role of an artificial gauge field. This will be illustrated on two examples : a weak link Josephson junction between two superconductors, and coupled cold atom Bose-Einstein condensates (BECs) where interactions play an essential role. Adiabatic to fast oscillating regimes will be explored, through resonant ones. This analogy offers a basis for quantum simulations of superconducting circuits by tunable BECs.
