Overlap Quark Propagator in Coulomb Gauge QCD
Ydalia Delgado Mercado, Markus Pak, Mario Schröck
The chirally symmetric Overlap quark propagator is explored in Coulomb gauge. This gauge is well suited for studying the relation between confinement and chiral symmetry breaking,…
The Z3 model with the density of states method
Ydalia Delgado Mercado, Pascal Törek, Christof Gattringer
In this contribution we apply a new variant of the density of states method to the Z3 spin model at finite density. We use restricted expectation values evaluated with Monte Carlo…
Taylor- and fugacity expansion for the effective Z(3) spin model of QCD at finite density
Eva Grünwald, Ydalia Delgado Mercado, Christof Gattringer
Series expansions in the chemical potential mu are studied for an effective theory of QCD which has a flux representation where the complex action is overcome. In particular we con…
Solving the sign problem of two flavor scalar electrodynamics at finite chemical potential
Ydalia Delgado Mercado, Christof Gattringer, Alexander Schmidt
We explore two flavor scalar electrodynamics on the lattice, which has a complex phase problem at finite chemical potential. By rewriting the action in terms of dual variables this…
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…
