Properties of canonical fermion determinants with a fixed quark number
Julia Danzer, Christof Gattringer, Ludovit Liptak
Using a dimensional reduction formula for the lattice fermion determinant we study canonical determinants on quenched SU(3) gauge configurations. The canonical determinants decribe…
A study of the sign problem for lattice QCD with chemical potential
Julia Danzer, Christof Gattringer, Ludovit Liptak +1
We study the expectation value of the phase of the fermion determinant for Wilson lattice fermions with chemical potential. We use quenched SU(3) ensembles and implement a recently…
Canonical fermion determinants in lattice QCD - Numerical evaluation and properties
Erek Bilgici, Julia Danzer, Christof Gattringer +2
We analyze canonical fermion determinants, i.e., fermion determinants projected to a fixed quark number q. The canonical determinants are computed using a dimensional reduction for…
Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric…
Thermodynamical quantities for overlap fermions with chemical potential
Christof Gattringer, Ludovit Liptak
Recently a formulation of overlap fermions at finite density based on an analytic continuation of the sign function was proposed. We study this proposal by analyzing the energy and…
Energy density for chiral lattice fermions with chemical potential
Christof Gattringer, Ludovit Liptak
We study a recently proposed formulation of overlap fermions at finite density. In particular we compute the energy density as a function of the chemical potential and the temperat…
