The Many Body Physics of Hot Dense Matter

I will discuss equation of state and spin-isospin
correlations of hot and dense nucleonic matter found in supernovae and
proto-neutron stars. The calculations are done using an ab
initio variational many body technique, where the only inputs are the
two nucleon and three nucleon interactions in free space. Recently, we
showed how a variational theory can be constructed for a system of
fermions at finite temperature, which can fully exploit the powerful
chain summation techniques developed for theories at zero temperature. I
will present results using this method and discuss the consequences for
the fate of neutral pion condensation at finite temperature.
