Abstract

Although simple theoretical descriptions of the Shapiro effect focus on a voltage biased superconducting Josephson junction, experimental measurements are predominantly made using current biased systems. In an analogous superfluid ³He system, a Josephson weak link can be predominantly pressure biased in accordance with the simple theory. Here, we use numerical methods to reproduce new features found in the observed "superfluid Shapiro effect". We find the proper characteristics for a pressure biased system with new additional structure resulting from a non-zero source resistance.
