Thermodynamical consistency of quasiparticle model at finite baryon density

Towards thermodynamical consistency of quasiparticle picture

The purpose of the present article is to call attention to some realistic quasiparticle-based description of the quark/gluon matter and its consistent implementation in thermodynamics. A simple and transparent representation of the thermodynamical consistency conditions is given. This representation allows one to review critically and systemize available phenomenological approaches to the decon...

The 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...

Strongly Coupled QCD at Finite Baryon Density

Finite Density QCD is affected by the well known sign problem that has prevented, in most cases, any success in simulate this theory and, until now, no solution is at sight. The only exceptions in this scenario are strong coupling simulations performed with the Monomer Dimer Polymer (MDP) algorithm [1]. This algorithm is able to provide results not affected by early onset and in partial agreeme...

Microscopic baryon-baryon interactions at finite density and hypernuclear structure

Oscillations of the Static Meson Fields at Finite Baryon Density

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.
