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…
Screening properties and phase transitions in unconventional plasmas for Ising-type quantum Hall states
Egil Herland, Egor Babaev, Parsa Bonderson +3
Utilizing large-scale Monte-Carlo simulations, we investigate an unconventional two-component classical plasma in two dimensions which controls the behavior of the norms and overla…
Deconfined quantum criticality and logarithmic violations of scaling from emergent gauge symmetry
Flavio S. Nogueira, Asle Sudbo
We demonstrate that the low-energy effective theory for a deconfined quantum critical point in dimensions contains a leading order contribution given by the Faddeev-Skyrme…
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…
