Description
A chiral model based on nucleons interacting via boson exchange is investigated. Fluctuation effects are then included consistently beyond the mean-field approximation in the framework of the functional renormalization group. The liquid-gas phase transition of symmetric nuclear matter is studied in detail. No sign of a chiral restoration is found up to 100 MeV temperature and about three times saturation density. Moreover, the model is extended to asymmetric nuclear matter. The constraints from neutron star observations are discussed.
