Abstract:

Superfluid Josephson weak links were established by studying the mass currents through the links in the presence of an externally applied ac pressure modulation. A superfluid analog of the superconducting Shapiro effect in Josephson weak links was obtained. Chararacteristic changes in dc mass currents were observed when the superfluid Josephson frequency happened to be an integral multiple of the ac modulation frequency ω. The dependence of current changes on ac pressure amplitude were in agreement with the theory describing quantum phase dynamics of superfluid weak links.
