Query: Superconductor-Insulator Transition and the Crossover to Non Equilibrium
  in two-dimensional Indium - Indium-Oxide composite   Magnetic-field tuned superconductor to insulator transition was observed in a
novel hybrid system of granular superconducting indium, deposited on indium
oxide thin film, which exhibits global superconductivity at low magnetic
fields. We have used annealing to tune the coupling to lie just at the
borderline where superconductivity in the underlying InOx is suppressed, which
is also close to the metal-insulator transition of the InOx. The hybrid system
exhibits a "giant" magnetoresistance above the H-SIT, with critical behavior
that manifests the duality between Cooper pairs and vortices.
