Topological order and the deconfinement transition in the (2+1) dimensional compact Abelian Higgs model
Anders Vestergren, Jack Lidmar
We study an Abelian compact gauge theory minimally coupled to bosonic matter with charge q, which may undergo a confinement--deconfinement transition in (2+1)D. The transition is a…
The Effect of Columnar Disorder on the Superconducting Transition of a Type-II Superconductor in Zero Applied Magnetic Field
A. Vestergren, M. Wallin, S. Teitel +1
We investigate the effect of random columnar disorder on the superconducting phase transition of a type-II superconductor in zero applied magnetic field using numerical simulations…
Topological Order in the (2+1)D Compact Lattice Superconductor
Anders Vestergren, Jack Lidmar, T. H. Hansson
We study topological aspects of a compact lattice superconductor, and show that the characteristic energy splitting, , between almost degenerate ground states, is simply related…
Unscreened universality class for superconductors with columnar disorder
Anders Vestergren, Jack Lidmar, Mats Wallin
The phase transition in a model for vortex lines in high temperature superconductors with columnar defects, i.e., linearly correlated quenched random disorder, is studied with fini…
Vortex glass transition in a random pinning model
Anders Vestergren, Jack Lidmar, Mats Wallin
We study the vortex glass transition in disordered high temperature superconductors using Monte Carlo simulations. We use a random pinning model with strong point-correlated quench…
