Functional Renormalization Group Study of the Chiral Phase Transition Including Vector and Axial-vector Mesons
Jürgen Eser, Mara Grahl, Dirk H. Rischke
The transition in quantum chromodynamics (QCD) from hadronic matter to the quark-gluon plasma (QGP) at high temperatures and/or net-baryon densities is associated with the restorat…
U(2)xU(2)-symmetric fixed point from the Functional Renormalization Group
Mara Grahl
The existence of an U(2)xU(2)-symmetric fixed point in the chiral linear sigma model is confirmed using the Functional Renormalization Group (FRG). Its stability properties and the…
Functional renormalization group study of the two-flavor linear sigma model in the presence of the axial anomaly
Mara Grahl, Dirk H. Rischke
The -symmetric chiral linear sigma model in the presence of the axial anomaly is studied in the local-potential approximation of the Functional Renormalizati…
The O(2) model in polar coordinates at nonzero temperature
Mara Grahl, Elina Seel, Francesco Giacosa +1
We study the restoration of spontaneously broken symmetry at nonzero temperature in the framework of the O(2) model using polar coordinates. We apply the CJT formalism to calculate…
