Three distinct types of quantum phase transitions in a (2+1)-dimensional array of dissipative Josephson junctions
Einar B. Stiansen. Iver B. Sperstad, Asle Sudbø
We have performed large-scale Monte Carlo simulations on a model describing a (2+1)-dimensional array of dissipative Josephson junctions. We find three distinct stable quantum phas…

Monte Carlo simulations of dissipative quantum Ising models
Iver B. Sperstad, Einar B. Stiansen, Asle Sudbo
The dynamical critical exponent is a fundamental quantity in characterizing quantum criticality, and it is well known that the presence of dissipation in a quantum model has si…
