Vortex Proliferation and the Dual Superconductor Scenario for Confinement: The 3D Compact U(1) Lattice Higgs Model
Sandro Wenzel, Elmar Bittner, Wolfhard Janke +2
It is argued that the phase diagram of the 3D Compact U(1) Lattice Higgs Model is more refined than generally thought. The confined and Higgs phases are separated by a well-defined…
Vortex-line percolation in the three-dimensional complex |psi|^4 model
Elmar Bittner, Axel Krinner, Wolfhard Janke
In discussing the phase transition of the three-dimensional complex |psi|^4 theory, we study the geometrically defined vortex-loop network as well as the magnetic properties of the…
Evaporation/Condensation of Ising Droplets
Andreas Nussbaumer, Elmar Bittner, Wolfhard Janke
Recently Biskup et al. [Europhys. Lett. 60 (2002) 21] studied the behaviour of d-dimensional finite-volume liquid-vapour systems at a fixed excess of particles above the ambie…
Vortex-Line Percolation in the Three-Dimensional Complex Ginzburg-Landau Model
Elmar Bittner, Axel Krinner, Wolfhard Janke
We study the phase transition of the three-dimensional complex |psi|^4 theory by considering the geometrically defined vortex-loop network as well as the magnetic properties of the…
Two-colour Lattice QCD with dynamical fermions at non-zero density versus Matrix Models
Gernot Akemann, Elmar Bittner
We provide first evidence that Matrix Models describe the low lying complex Dirac eigenvalues in a theory with dynamical fermions at non-zero density. Lattice data for gauge group…
Kertesz Line in the Three-Dimensional Compact U(1) Lattice Higgs Model
Sandro Wenzel, Elmar Bittner, Wolfhard Janke +2
The three-dimensional lattice Higgs model with compact U(1) gauge symmetry and unit charge is investigated by means of Monte Carlo simulations. The full model with fluctuating Higg…
Nature of Phase Transitions in a Generalized Complex |psi|^4 Model
Elmar Bittner, Wolfhard Janke
We employ Monte Carlo simulations to study a generalized three-dimensional complex $psi|^4 theory of Ginzburg-Landau form and compare our numerical results with a recent quasi-anal…
