Asymmetric 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 کاملHot 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 in the Relativistic Brueckner Hartree Fock approach
We present a calculation of asymmetric nuclear matter properties in a relativistic Brueckner Hartree Fock framework. Following other calculations the components of the self-energies are extracted by projecting on Lorentz invariant amplitudes. It is shown that for asymmetric nuclear matter one needs a sixth invariant. We present a set of invariants which in the limit of symmetric nuclear matter ...
متن کاملAsymmetric Nuclear Matter from Extended Brueckner-Hartree-Fock Approach
The properties of isospin-asymmetric nuclear matter have been investigated in the framework of the extended Brueckner-Hartree-Fock approximation at zero temperature. Selfconsistent calculations using the Argonne V14 interaction are reported for several asymmetry parameters β = N−Z A ranging from symmetric nuclear matter to pure neutron matter. The binding energy per nucleon fulfills the β law i...
