Vortices in equilibrium scalar electrodynamics
A. Rajantie, K. Kajantie, M. Karjalainen +2
Scalar electrodynamics can be used to investigate the formation of cosmic strings in the early universe. We present the results of lattice Monte Carlo simulations of an effective t…
Thermodynamics of Gauge-Invariant U(1) Vortices from Lattice Monte Carlo Simulations
K. Kajantie, M. Karjalainen, M. Laine +2
We study non-perturbatively and from first principles the thermodynamics of vortices in 3d U(1) gauge+Higgs theory, or the Ginzburg-Landau model, which has frequently been used as…
Three-dimensional U(1) gauge+Higgs theory as an effective theory for finite temperature phase transitions
K. Kajantie, M. Karjalainen, M. Laine +1
We study the three-dimensional U(1)+Higgs theory (Ginzburg-Landau model) as an effective theory for finite temperature phase transitions from the 1 K scale of superconductivity to…
Masses and Phase Structure in the Ginzburg-Landau Model
K. Kajantie, M. Karjalainen, M. Laine +1
We study numerically the phase structure of the Ginzburg-Landau model, with particular emphasis on mass measurements. There is no local gauge invariant order parameter, but we find…
The order of the phase transition in 3d U(1)+Higgs theory
M. Karjalainen, M. Laine, J. Peisa
We study the order of the phase transition in the 3d U(1)+Higgs theory, which is the Ginzburg-Landau theory of superconductivity. We confirm that for small scalar self-coupling the…
Dimensionally reduced U(1)+Higgs theory in the broken phase
Mika Karjalainen, Janne Peisa
We apply dimensional reduction to the finite temperature U(1)+Higgs theory and study the properties of the reduced 3-dimensional theory in the broken phase using lattice Monte Carl…
