Computer Simulations of the 3–Dimensional Abelian Higgs Model — •Sandro Wenzel, Elmar Bittner, Wolfhard Janke, and Arwed Schiller — Institut für Theoretische Physik, Universität Leipzig, Augustusplatz 10/11, 04109 Leipzig, Germany

Using multicanonical and heat–bath Monte Carlo algorithms we investigated the 3–dimensional Abelian Higgs model [1] on the lattice with compact gauge fields and fluctuating Higgs amplitudes (λ ≠ ∞). Special consideration was given to the first–order regime of the confinement–deconfinement phase transition. The existence and location of a (tri–)critical point was explored using reweighting techniques.
