Taylor- and fugacity expansion for the effective center model of QCD at finite density
Eva Grünwald, Ydalia Delgado Mercado, Christof Gattringer
Using the effective center model of QCD we test series expansions for finite chemical potential . In particular we study two variants of Taylor expansion as well as the fugacity…
Worm Algorithm for Abelian Gauge-Higgs Models
Ydalia Delgado, Alexander Schmidt
We present the surface worm algorithm (SWA) which is a generalization of the Prokof'ev Svistunov worm algorithm to perform the simulation of the dual representation (surfaces and l…
Flux simulation of the SU(3) spin model at finite chemical potential
Ydalia Delgado, Christof Gattringer
We present a Monte Carlo simulation of an effective theory for local Polyakov loops at finite temperature and density. The sign problem is overcome by mapping the partition sum to…
QCD thermodynamics with dynamical overlap fermions
S. Borsanyi, Y. Delgado, S. Durr +6
We study QCD thermodynamics using two flavors of dynamical overlap fermions with quark masses corresponding to a pion mass of 350 MeV. We determine several observables on N_t=6 and…
The QCD Phase Diagram with Effective Theories
Ydalia Delgado, Hans Gerd Evertz, Christof Gattringer +1
We study two effective theories for QCD at non-zero temperature and finite chemical potential, using local Polyakov loops as the degrees of freedom. The sign problem is solved by e…
Solving the Complex Phase Problem in a QCD Related Model
Ydalia Delgado, Hans Gerd Evertz, Christof Gattringer
We discuss an effective theory for QCD at finite chemical potential and non-zero temperature, where QCD is reduced to its center degrees of freedom. The effective action can be map…
