Time Dependent Relativistic Mean-field Theory
The relativistic mean-field theory provides a framework in which the nuclear manybody problem is described as a self-consistent system of nucleons and mesons. In the mean-field approximation, the self-consistent time evolution of the nuclear system describes the dynamics of collective motion: double giant resonances, nuclear compressibility from monopole resonances, regular and chaotic dynamics...
متن کاملNuclear Matter in Relativistic Mean Field Theory with Isovector Scalar Meson
Relativistic mean field (RMF) theory of nuclear matter with the isovector scalar mean field corresponding to the δ-meson [a0(980)] is studied. While the δ-meson mean field vanishes in symmetric nuclear matter, it can influence properties of asymmetric nuclear matter in neutron stars. The RMF contribution due to δ-field to the nuclear symmetry energy is negative. To fit the empirical value, Es ≈...
متن کاملNeutron Stars in Relativistic Mean Field Theory with Isovector Scalar Meson
We study the equation of state (EOS) of β-stable dense matter and models of neutron stars in the relativistic mean field (RMF) theory with the isovector scalar mean field corresponding to the δ-meson [a0(980)]. A range of values of the δ-meson coupling compatible with the Bonn potentials is explored. Parameters of the model in the isovector sector are constrained to fit the nuclear symmetry ene...
متن کاملRelativistic Mean-Field Model with Momentum-Dependent Self-Energies
The conventional relativistic mean-field model with minimal meson-nucleon couplings is extended by introducing derivative meson-nucleon couplings. Combining this approach with a density dependence of the coupling vertices leads to an improved description of nuclear matter and atomic nuclei, especially of effective masses and the optical potential. Introduction and Theoretical Model The relativi...
متن کاملSuperheavy nuclei with the vector self-coupling of the ω-meson in the relativistic mean-field theory
We have studied properties and shell structure of the superheavy elements from Z = 102 to Z = 120 within the framework of the RMF theory. The region of study spans nuclides with neutron numbers N = 150 − 190. The Lagrangian model NL-SV1 with the inclusion of the vector self-coupling of the ω-meson has been employed in this work. We have performed RMF + BCS calculations for an axially deformed c...
