Lee-Yang zeros and edge singularity in a mean-field approach
Tatsuya Wada, Győző Kovács, Masakiyo Kitazawa +1
The analytic structure of the partition function in finite-volume systems is investigated at complex chemical potentials in a minimal mean-field effective model of QCD with finite-…
Chiral anomaly: from vacuum to Columbia plot
Francesco Giacosa, Győző Kovács, Péter Kovács +2
We use a low-energy effective approach, the extended linear sigma model, to study realizations of the anomaly with different operators, linear and quadratic in the 't Hoof…
Finite-size effects and scaling properties of chiral and baryon-number fluctuations
Győző Kovács, Pok Man Lo, Krzysztof Redlich +1
An effective chiral model is introduced to illustrate finite-size effects, incorporating the standard zero-mode treatment, momentum-space discretization, and gradient effects model…
Naive Gaussian approximation in a quark-meson model
Győző Kovács, Zsolt Szép, Péter Kovács +1
A sequence of approximations is derived to go beyond the mean-field level in the case of a simple linear sigma model. A naive, local version of the Gaussian approximation is discus…
Finite size effects on the phase diagram and the baryon fluctuations via momentum space constraints
Győző Kovács
The effect of the finite system size on the QCD phase diagram was studied with various momentum space constraints within a mean-field quark-meson model. On the one hand side, the c…
One-loop constituent quark contributions to the vector and axial-vector meson curvature mass
Győző Kovács, Péter Kovács, Zsolt Szép
The renormalized contribution of fermions to the curvature masses of vector and axial-vector mesons is derived with two different methods at leading order in the loop expansion app…
