Polyakov loops and spectral properties of the staggered Dirac operator
Falk Bruckmann, Stefan Keppeler, Marco Panero +1
We study the spectrum of the staggered Dirac operator in SU(2) gauge fields close to the free limit, for both the fundamental and the adjoint representation. Numerically we find a…
Dual quark condensate and dressed Polyakov loops
Erek Bilgici, Falk Bruckmann, Christof Gattringer +1
We construct a new order parameter for finite temperature QCD by considering the quark condensate for U(1)-valued temporal boundary conditions for the fermions. Fourier transformat…
Smearing and filtering methods in lattice QCD - a quantitative comparison
Stefan Solbrig, Falk Bruckmann, Christof Gattringer +3
We systematically compare three filtering methods used to extract topological excitations from lattice gauge configurations, namely smearing, Laplace filtering and the filtered fer…
Exploring the QCD vacuum - (some) recent developments in confinement and topology
Falk Bruckmann
I start by giving a brief overview over new developments in the area of confinement and topology. As an example for the interrelations between topological objects, instantons at fi…
Thin and dressed Polyakov loops from spectral sums of lattice differential operators
Erek Bilgici, Christian Hagen, Falk Bruckmann +1
We represent thin and dressed Polyakov loops as spectral sums of eigenvalues of differential operators on the lattice. For that purpose we calculate complete sets of eigenvalues of…
Instanton constituents in the O(3) model at finite temperature
Falk Bruckmann
It is shown that instantons in the O(3) model at finite temperature consist of fractional charge constituents and the (topological) properties of the latter are discussed.
