Quantum Corrections on Relativistic Mean Field Theory for Nuclear Matter

K-Nuclear Bound States in Relativistic Mean-Field Theory

We have developed the relativistic mean field model to the study of kaonic nuclei. Starting with the Lagrangian for nucleons and (anti)kaon meson, the equations of motion for nucleon field, scalar meson, vector meson and (anti)kaon meson fields are deduced. By self-consistently solving the equations of motion, the K−-nuclear deeply bound states are obtained for the nuclei with A ≥ 8. The K−-nuc...

Semiclassical Approach to Relativistic Nuclear Mean Field Theory

Nuclear Breathing Mode in the Relativistic Mean-field Theory

The breathing-mode giant monopole resonance is studied within the framework of the relativistic mean-field (RMF) theory. Using a broad range of parameter sets, an analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. It is shown that the non-linear scalar self-interaction considerably. It is observed that dynamical surface pr...

Nuclear 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 ≈...

Nuclear Matter with a Bose Condensate of Dibaryons in Relativistic Mean-Field Theory

If sufficiently light dibaryon resonances exist, a Bose condensate of dibaryons can occur in nuclear matter before the quark-hadron phase transition. Within a relativistic mean-field model we show that heterophase nuclear-dibaryon matter is for a wide set of parameters energetically more favorable than normal nuclear matter. Production of dibaryons is, however, relatively suppressed as compared...
