Nuclear symmetry energy and its density slope at normal density extracted from global nucleon optical potentials
Chang Xu, Bao-An Li, Lie-Wen Chen
Based on the Hugenholtz-Van Hove theorem, it is shown that both the symmetry energy E and its density slope at normal density are completely determined by t…
Analytical relations between nuclear symmetry energy and single-nucleon potentials in isospin asymmetric nuclear matter
Chang Xu, Bao-An Li, Lie-Wen Chen +1
Using the Hugenholtz-Van Hove theorem, we derive general expressions for the quadratic and quartic symmetry energies in terms of single-nucleon potentials in isospin asymmetric nuc…
Density slope of the nuclear symmetry energy from the neutron skin thickness of heavy nuclei
Lie-Wen Chen, Che Ming Ko, Bao-An Li +1
Expressing explicitly the parameters of the standard Skyrme interaction in terms of the macroscopic properties of asymmetric nuclear matter, we show in the Skyrme-Hartree-Fock appr…
Transition density and pressure in hot neutron stars
Jun Xu, Lie-Wen Chen, Che Ming Ko +1
Using the momentum-dependent MDI effective interaction for nucleons, we have studied the transition density and pressure at the boundary between the inner crust and liquid core of…
Isospin- and momentum-dependent effective interactions for the baryon octet and the properties of hybrid stars
Jun Xu, Lie-Wen Chen, Che Ming Ko +1
The isospin- and momentum-dependent MDI interaction, which has been extensively used in intermediate-energy heavy-ion reactions to study the properties of asymmetric nuclear matter…
