Query: Josephson effects in a superconductor-normal metal mesoscopic structure
  with a dangling superconducting arm   We studied a mesoscopic cross-like normal metal structure connected to two
superconducting (S) and two normal (N) reservoirs. We observed the Josephson
effect under unusual conditions when there is no current through one of the two
S/N interfaces. The potential difference between the S reservoirs was zero
unless the voltage applied between S and N reservoirs exceeded a critical value
although the electric potential in the N wire connecting the superconductors
varied in a nonmonotonic way. The observed effects are discussed theoretically.
