High Density Fluctuations in Neutron Stars — •Konstantin Otto¹, Micaela Oertel², Mario Mitter³, and Bernd-Jochen Schaefer¹ — ¹Institut für Theoretische Physik, Justus-Liebig-Universität Gießen, Germany — ²Observatoire de Paris, CNRS, Meudon, France — ³Department of Physics, BNL, Upton, NY 11973

The impact of thermal and quantum fluctuations at high baryon chemical potential on neutron stars is studied in the framework of the functional renormalization group (FRG) analysis with a quark-meson model truncation. Results for both N_f=2 and N_f=2+1 quark flavors are compared with each other such that the role of strangeness in compact objects can be addressed. The effect of vacuum fluctuations on the equation of state is investigated with corresponding mean-field approximations.
