Quantum criticality in a dissipative (2+1)-dimensional XY model of circulating currents in high-Tc cuprates
Iver Bakken Sperstad, Einar B. Stiansen, Asle Sudbø
We present large-scale Monte Carlo results for the dynamical critical exponent z and the spatio-temporal two-point correlation function of a (2+1)-dimensional quantum XY model with…

Criticality of compact and noncompact quantum dissipative models in dimensions
Einar B. Stiansen, Iver Bakken Sperstad, Asle Sudbø
Using large-scale Monte Carlo computations, we study two versions of a -symmetric model with Ohmic bond dissipation. In one of these versions, the variables are restr…
