Title : The Many Body Physics of Hot Dense Matter
Abstract : 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.
