Finite-size effects and scaling properties of chiral and baryon-number fluctuations
GyÅzÅ 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…
Lee-Yang zeros and edge singularity in a mean-field approach
Tatsuya Wada, GyÅzÅ 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, GyÅzÅ 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…
Naive Gaussian approximation in a quark-meson model
GyÅzÅ 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
GyÅzÅ 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…
