New overlap construction of Weyl fermions
Christof Gattringer, Markus Pak
In a recent article Hasenfratz and von Allmen have suggested a fixed point action for two flavors of Weyl fermions on the lattice with gauge group SU(2). The block-spin transformat…
Derivative sources in lattice spectroscopy of excited light-quark mesons
Christof Gattringer, Leonid Ya. Glozman, C. B. Lang +2
We construct efficient interpolating fields for lattice spectroscopy of mesons by applying covariant derivatives on Jacobi smeared quark sources. These interpolators are tested in…
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…
Excited State Spectroscopy in the Lattice Gross-Neveu Model
Julia Danzer, Christof Gattringer
We present preliminary results of an excited state spectroscopy calculation in the 2-d lattice Gross-Neveu model. We address the construction of suitable interpolators for the vari…
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…
Meson spectroscopy with derivative quark sources
Christof Gattringer, Leonid Ya. Glozman, C. B. Lang +2
We present results for masses of light mesons obtained with the variational method using an enhanced basis of interpolating field operators with different quark smearings. The inte…
