Query: Rectification by imprinted phase in a Josephson junction   A Josephson phase shift can be induced in a Josephson junction by a
strategically nearby pinned Abrikosov vortex (AV). For an asymmetric
distribution of imprinted phase along the junction (controlled by the position
of the AV) such a simple system is capable of rectification of $ac$ current in
a broad and tunable frequency range. The resulting rectified voltage is a
consequence of the directed motion of a Josephson antivortex which forms a pair
with the AV when at local equilibrium. The proposed realization of the ratchet
potential by imprinted phase is more efficient than the asymmetric geometry of
the junction itself, it is easily realizable experimentally, and provides
rectification even in the absence of applied magnetic field.
