Oscillations of the Static Meson Fields at Finite Baryon Density
نویسندگان
چکیده
The spatial dependence of static meson correlation functions at finite baryon density is studied in the Nambu – Jona-Lasinio model. In contrast to the finite temperature case, we find that the correlation functions at finite density are not screened but exhibit long-range oscillations. The observed phenomenon is analogous to the Friedel oscillations in a degenerate electron gas.

Abstract We discuss the relation between the effective vector meson mass and equation of state (EOS) for nuclear matter. In the mean field approximation, the EOS becomes softer due to the reduction of the effective ω-meson mass, if we assume that the ω-meson mean field is proportional to the baryon density. We examine the assumption by using the auxiliary field method at finite temperature and ...
متن کاملMeson-Meson and Meson-Baryon Interactions in Lattice QCD
We study the meson-meson and meson-baryon interactions in lattice QCD. The simulation is performed on 203 × 24 lattice at β = 5.7 using Wilson gauge action and Wilson fermion at the quenched level. By adopting one static quark for each hadron as “heavy-light meson" and “heavy-light-light baryon", we define the distance r of two hadrons and extract the inter-hadron potential from the energy diff...
متن کاملThe Chiral Model of Sakai-Sugimoto at Finite Baryon Density
In the context of holographic QCD we analyze Sakai-Sugimoto’s chiral model at finite baryon density and zero temperature. The baryon number density is introduced through compact D4 wrapping S4 at the tip of D8-D8. Each baryon acts as a chiral point-like source distributed uniformly over R3, and leads a non-vanishing U(1)V potential on the brane. For fixed baryon charge density nB we analyze the...

متن کاملQuantum Vacuum in Hot Nuclear Matter – A Nonperturbative Treatment
We derive the equation of state for hot nuclear matter using Walecka model in a nonperturbative formalism. We include here the vacuum polarisation effects arising from the nucleon and scalar mesons through a realignment of the vacuum. A ground state structure with baryon-antibaryon condensates yields the results obtained through the relativistic Hartree approximation (RHA) of summing baryonic t...
