Correlations 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 کاملSpatially inhomogeneous condensate in asymmetric nuclear matter
We study the isospin singlet pairing in asymmetric nuclear matter with nonzero total momentum of the condensate Cooper pairs. The quasiparticle excitation spectrum is fourfold split compared to the usual BCS spectrum of the symmetric, homogeneous matter. A twofold splitting of the spectrum into separate branches is due to the finite momentum of the condensate, the isospin asymmetry, or the fini...
متن کاملPhase transitions in warm, asymmetric nuclear matter.
A relativistic meaneld model of nuclear matter with arbitrary proton fraction is studied at nite temperature. An analysis is performed of the liquid{ gas phase transition in a system with two conserved charges (baryon number and isospin) using the stability conditions on the free energy, the conservation laws, and Gibbs' criteria for phase equilibrium. For a binary system with two phases, the c...
متن کاملNucleation Process in Asymmetric Nuclear Matter
An extended version of the non linear Walecka model, with ρ mesons and eletromagnetic field is used to investigate the possibility of phase transitions in hot (warm) nuclear matter, giving rise to droplet formation. Surface properties of asymmetric nuclear matter as the droplet surface energy and its thickness are also examined. PACS number(s):21.65.+f, 21.90.+f,26.60.+c
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...
