Hot nuclear matter : A variational approach
We develop a nonperturbative technique in field theory to study properties of infinite nuclear matter at zero temperature as well as at finite temperatures. Here we dress the nuclear matter with off-mass shell pions. The techniques of thermofield dynamics are used for finite temperature calculations. Equation of state is derived from the dynamics of the interacting system in a self consistent m...
متن کاملAsymmetric Nuclear Matter : A variational Approach
We discuss here a self-consistent method to calculate the properties of the cold asymmetric nuclear matter. In this model, the nuclear matter is dressed with s-wave pion pairs and the nucleonnucleon (N-N) interaction is mediated by these pion pairs, ω and ρ mesons. The parameters of these interactions are calculated self-consistently to obtain the saturation properties like equilibrium binding ...
متن کاملVariational Calculations of Asymmetric Nuclear Matter
We report on variational calculations of the energy E(p, ß) of asymmetric nuclear matter having p = p +pp = 0.05 to 0 .35 fm-~, and ß = (P -p~)lp = 0 to l . The nuclear hamiltonian used in this work consists of a realistic two-nucleon interaction, called °i<, that fits the available nucleon-nucleon scattering data up to 425 MeV, and a phenomenological three nucleon interaction adjusted to repro...
متن کاملThe exploration of hot nuclear matter.
When nuclear matter is heated beyond 2 trillion degrees, it becomes a strongly coupled plasma of quarks and gluons. Experiments using highly energetic collisions between heavy nuclei have revealed that this new state of matter is a nearly ideal, highly opaque liquid. A description based on string theory and black holes in five dimensions has made the quark-gluon plasma an archetypical strongly ...
متن کاملCorrelations in hot asymmetric nuclear matter
The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green’s functions. The internal energy and the momentum distributions of protons and neutrons are studied as a function of the density and the asymmetry of the system. The proton states are more strongly depleted when the asymmetry increases whe...
