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…
Monte Carlo simulation of the SU(3) spin model with chemical potential in a flux representation
Ydalia Delgado Mercado, Christof Gattringer
We present a simulation of the SU(3) spin model with chemical potential using a recently proposed flux representation. In this representation the complex phase problem is avoided a…
Worm algorithms for the 3-state Potts model with magnetic field and chemical potential
Ydalia Delgado, Hans Gerd Evertz, Christof Gattringer
We discuss worm algorithms for the 3-state Potts model with external field and chemical potential. The complex phase problem of this system can be overcome by using a flux represen…
