The neutron matter equation of state from low-momentum interactions
L. Tolos, B. Friman, A. Schwenk
Abstract
We calculate the neutron matter equation of state at finite temperature based on low-momentum nucleon-nucleon and three-nucleon interactions. Our results are compared to the model-independent virial equation of state and to variational calculations. We provide a simple estimate for the theoretical error, important for extrapolations to astrophysical conditions.
