Abstract

Effects of interaction between two superconducting weak links (SWL) at V=0 have been calculated using the Ginzburg-Landau theory. Variations of the critical current of one SWL affected by a dc current in a neighboring SWL are found in good qualitative agreement with a recent experiment. The current-phase relation of the combined system is computed for various separations between the two SWL's; it is shown explicitly that the system behaves as a single SWL when the spacing between links is comparable to the coherence length.
