Critical dynamics, duality, and the exact dynamic exponent in extreme type II superconductors
Flavio S. Nogueira, Dirk Manske
The critical dynamics of superconductors is studied using renormalization group and duality arguments. We show that in extreme type II superconductors the dynamic critical exponent…
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…
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…
Field Theoretical Approaches to the Superconducting Phase Transition
Flavio S. Nogueira, Hagen Kleinert
Several field theoretical approaches to the superconducting phase transition are discussed. Emphasis is given to theories of scaling and renormalization group in the context of the…
Spin Josephson effect in ferromagnet/ferromagnet tunnel junctions
Flavio S. Nogueira, Karl-Heinz Bennemann
We consider the tunnel spin current between two ferromagnetic metals from a perspective similar to the one used in superconductor/superconductor tunnel junctions. We use fundamenta…
