Metal-Insulator Transition in Two- and Three-Dimensional Logarithmic Plasmas
S. Kragset, A. Sudbo, F. S. Nogueira
We consider scaling of the mean square dipole moments in a plasma with logarithmic interactions in a two- and three-dimensional system. In both cases, we establish the existence of…
Phase structure of Abelian Chern-Simons gauge theories
E. Smorgrav, J. Smiseth, A. Sudbo +1
We study the effect of a Chern-Simons (CS) term in the phase structure of two different Abelian gauge theories. For the compact Maxwell-Chern-Simons theory, we obtain that for valu…
Compact U(1) gauge theories in 2+1 dimensions and the physics of low dimensional insulating materials
F. S. Nogueira, J. Smiseth, E. Smoergrav +1
Compact abelian gauge theories in dimensions arise often as an effective field-theoretic description of models of quantum insulators. In this paper we review some recent re…
Deconfinement mechanism in three dimensions for gauge fields coupled to bosonic matter fields with fundamental charge
Flavio S. Nogueira, Asle Sudbo
We propose a mechanism by which electric charges deconfine in an Abelian Higgs model with matter fields belonging to the fundamental representation of the gauge group. Kosterlitz-T…

Criticality versus q in the 2+1-dimensional clock model
J. Hove, A. Sudbo
Using Monte Carlo simulations we have studied the clock model in two different representations, the phase-representation and the loop/dumbbell-gas (LDG) representation.…
