Phase Diagram for Superconductor-Insulator Transition in Single Small Josephson Junctions with Shunt Resistor

Abstract

We studied the effect of the energy dissipation in single small Josephson junctions by attaching external shunt resistors. We observed a superconductor-insulator (S-I) transition driven by the shunt resistor. We determined the phase diagram for the S-I transition experimentally.
