Kinetics of Chiral Phase Transitions in Quark Matter
Kinetics Chiral Phase Transitions Quark Matter
2011/7/21
We study the kinetics of chiral transitions in quark matter using a microscopic framework (Nambu-Jona-Lasinio model) and a phenomenological model (Ginzburg-Landau free energy).
We study the QCD phase diagram at finite temperature and baryon chemical potential by relating the behavior of the light-quark condensate to the threshold energy for the onset of perturbative QCD.
In this paper we discuss the possibility that chiral phase transitions, analogous to those of QCD, occur in the vicinity of a black hole.
On critical scaling at the QCD N_f=2 chiral phase transition
chiral phase transition critical scaling at the QCD N_f=2
2011/7/21
We investigate the critical scaling of the quark propagator of N_f=2 QCD close to the chiral phase transition at finite temperature. We argue that it is mandatory to take into account the back-reactio...

We deduce approximate equations of state from experimental measurements in proton-proton and proton-antiproton collisions.
Nuclear matter and chiral phase transition at large-$N_{c}$
Institute of theoretical Physics, Johann Wolfgang Goethe University
2011/7/21
Two aspects of the QCD phase diagrams are studied in the limit of a large number of colors: at zero temperature and nonzero density the (non)existence of nuclear matter, and at zero density and nonzer...
The dynamics of partons, hadrons and strings in relativistic nucleus-nucleus collisions is analyzed within the novel Parton-Hadron-String Dynamics (PHSD) transport approach, which is based on a dynami...

2011/1/6
In this paper, we calculate the diffusion coefficients that are related to the neutrino opacities considering the formation of nuclear pasta and homogeneous matter at low densities. Our results show t...

2011/1/6
The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model with the Skyrme effective interaction. By providing the analysis of the selfco...

2009/10/28
Some special issues of the random phase approximation(RPA) in the relativistic approach are reviewed. A full consistency and proper treatment of coupling to the continuum are responsible for the succe...
