Monte Carlo simulation of abelian gauge-Higgs lattice models using dual representation
Alexander Schmidt, Ydalia Delgado Mercado, Christof Gattringer
We study abelian gauge-Higgs models on the lattice and consider gauge groups Z(3) and U(1). For both cases the partition sums are mapped exactly to a dual representation where the…
Surface worm algorithm for abelian Gauge-Higgs systems on the lattice
Ydalia Delgado, Christof Gattringer, Alexander Schmidt
The Prokof'ev Svistunov worm algorithm was originally developed for models with nearest neighbor interactions that in a high temperature expansion are mapped to systems of closed l…
Gauge and matter fields as surfaces and loops - an exploratory lattice study of the Z(3) Gauge-Higgs model
Christof Gattringer, Alexander Schmidt
We discuss a representation of the Z(3) Gauge-Higgs lattice field theory at finite density in terms of dual variables, i.e., loops of flux and surfaces. In the dual representation…
