Superconductor-insulator quantum phase transition in a single Josephson junction

, 2001
The superconductor-to-insulator quantum phase transition in resistively shunted Josephson junctions is investigated by means of path-integral Monte Carlo simulations.

Design method of negative capacitor circuit for piezoelectric shunt damping in the presence of parasitic resistances

Nihon Kikai Gakkai ronbunshu, 2015
The parasitic resistances of a piezoelectric element have been often neglected in the conventional analysis of a piezoelectric shunt damping system. This paper indicates that the parasitic resistances cause instability in the piezoelectric shunt damping ...

A cluster algorithm for resistively shunted Josephson junctions

, 2004
We present a cluster algorithm for resistively shunted Josephson junctions and similar physical systems, which dramatically improves sampling efficiency. The algorithm combines local updates in Fourier space with rejection-free cluster updates which exploit the symmetries of the Josephson coupling energy. As an application, we consider the localization
