Intrinsic fluctuation effects and certain other aspects of superconducting weak links
The authors have experimentally observed the current-voltage behavior of various sorts of superconducting weak links, with and without applied electromagnetic fields. Observations have extended into the experimentally difficult regime very close to T(c).
