Description
Functional renormalization group (FRG) is an exact method for taking
into account the effect of quantum fluctuations in the effective action of the
system. The FRG method applied to effective theories of nuclear matter yields
equation of state witch incorporates quantum fluctuations of the fields.
Using the local potential approximation the equation of state for Walecka-type
models of nuclear matter under extreme conditions is determined. These models
are tested by solving the corresponding Tollman-Oppenheimer-Volkov (TOV) equations
and investigating the properties (mass and radius) of the corresponding compact
star models.
