"The many facets of sQGP: EM duality, fluidity. "
Abstract
In the last ten years, the RHIC experiments have shown the creation of a dramatic form of hot QCD matter that expands like a "perfect fluid" and
strongly quenches high energy jets. These findings imply the underlying
microscopic dynamics is still strongly coupled (sQGP), thus opening windows
for nonperturbative emergent degrees of freedom. In this talk I will
discuss a possible "magnetic scenario" which describes the near Tc plasma as
a mixture of both colorelectric charges (quarks,gluons) and colormagnetic
monopoles. An overview on the theoretical motivation, lattice evidence, and
phenomenological implications will be given. I will then end this talk with
a brief discussion on a question of more general interests: how "perfect"
this QCD fluid is as compared with e.g. water. This first concerns what is a
quality measure of fluidity: a proposal will be made and used to compare
various fluids.

"Charmonium spectral functions in quarkgluon plasma from lattice QCD"
Abstract
From phenomenological considerations, J/psi suppression was proposed as a signature of QGP production in relativistic heavy ion collisions, and has been considered as one of the most promising ones in relativistic heavy ion collisions. On the other hand, previous studies with lattice QCD and effective theories show possibility of existence of q\bar{q} correlations even above the critical temperature. We study the charmonium spectral functions in quarkgluon plasma on 64^3 X Nt quenched anisotropic lattices, analyzing correlation functions of charmonium by the maximum entropy method (MEM). In particular we focus on a finite momentum effect on the charmonium spectral functions in order to understand J/Psi suppression mechanism in relativistic heavy ion collisions from the first principles of QCD.

"SPINODAL INSTABILITIES IN NUCLEAR MATTER IN A STOCHASTIC RELATIVISTIC MEANFIELD APPROACH"
Abstract
Spinodal instabilities and early growth of baryon density fluctuations in symmetric nuclear matter are investigated in the basis of the stochastic extension of the relativistic meanfield approach in the semiclassical approximation. The system exhibits most unstable behavior at higher baryon densities around \rho = 0.4 \rho_0
