  journal={arXiv: High Energy Physics - Phenomenology},
Nonperturbative equations of state (EoSs) for two and three quark flavors are constructed with the functional renormalization group (FRG) within a quark-meson model truncation augmented by vector mesons for low temperature and high density. Based on previous FRG studies without repulsive vector meson interactions the influence of isoscalar vector $\omega$- and $\phi$-mesons on the dynamical fluctuations of quarks and (pseudo)scalar mesons is investigated. The grand potential as well as vector… Expand

Remarks on nuclear matter: How an ω0 condensate can spike the speed of sound, and a model of Z(3) baryons
Robert D. Pisarski Department of Physics, Brookhaven National Laboratory, Upton, NY 11973 I make two comments about nuclear matter. First, I consider the effects of a coupling ∼ +ω μ ~ φ 2 betweenExpand
Shocks and quark-meson scatterings at large density
We discuss the phase structure of the two-flavour quark-meson model including quantum, thermal, density and critical fluctuations with the functional renormalisation group. This study combines twoExpand

The equation of state (EoS) of hot and dense matter is a fundamental input to describe static and dynamical properties of neutron stars, core-collapse supernovae and binary compact-star mergers. WeExpand
