Ratchet potential
The periodic effective potential of a superconducting quantum interference device containing an underdamped Josephson junction in the first branch and a double-barrier junction in the second is studied. An effective non-sinusoidal expression for the current–phase relation with an additional half harmonic term is used for the double-barrier junction. The system allows voltage rectification under opportunely chosen parameter values
