Novel effects of electromagnetic interaction on the correlation of nucleons in nuclear matter
The electromagnetic(EM) interactions between charged protons on the
correlations of nucleons are discussed by introducing the Anderson-Higgs
mechanism of broken U(1) EM symmetry into the relativistic nuclear theory with
a parametric photon mass. The non-saturating Coulomb force contribution is
emphasized on the equation of state of nuclear matter with charge symmetry
breaking(CSB) at finite temperature and the breached pairing
correlations of proton-proton and neutron-neutron. The universal properties
given by an order parameter field with a non-zero vacuum expectation value
(VEV) nearby phase transition are explored within the mean field theory(MFT)
level. This mechanism can be extended to the charged or charge neutralized
strongly coupling multi-components system for the discussion of binding or
pairing issues.Comment: 6 pages, 3 figues, revised according to comments; improved with typos
