Realistic and Effective Interactions in the Study of Nuclear Matter
The equation of state of symmetric nuclear matter is addressed starting both from a realistic interaction derived from nucleon-nucleon scattering processes and from a low-momentum effective potential. The approach is based on finite temperature Green's functions. The internal energy per particle is estimated from the summation of diagrams and through the Galitskii-Koltun's sum rule. At present,...
متن کاملCorrelations in Exotic Nuclear Matter
In recent years, the interest in correlations inside nuclei became an important issue in nuclear physics. On the theoretical, side several calculations using different models including short-range correlation have been done for nuclear matter. However, there is still not much known about the role of correlations in neutron star matter containing hyperons. In our work we examined dynamical corre...
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...
متن کاملShort-range correlations in asymmetric nuclear matter
The spectral function of protons in the asymmetric nuclear matter is calculated in the self-consistent T -matrix approach. The spectral function per proton increases with increasing asymmetry. This effect and the density dependence of the spectral function partially explain the observed increase of the spectral function with the mass number of the target nuclei in electron scattering experiment...
متن کاملBaryon Interactions in Nuclear and Hypernuclear Matter
The production and structure of Λ hypernuclei are investigated in field theoretical models. The production in coherent p+A reactions is investigated by means of a resonance model. Results of exploratory calculations for associated strangeness production are presented for proton reactions on 40Ca. The target single particle wave functions are obtained from DDRH theory with density dependent Dira...
