Resistively shunted Josephson junctions: quantum field theory predictions versus Monte Carlo results
Abstract
During the last fourteen years several exact results have been obtained for the so-called boundary sine Gordon model. In the case of a conformal bulk this 2D boundary quantum field theory describes the universal scaling behaviour of the Caldeira Leggett model of resistively shunted Josephson junctions. In this work, we use a recently developed Monte Carlo technique to test some of the analytical predictions.
