Title: "Isospin diffusion: Hydrodynamics and beyond through AdS/CFT?"
                                                                               
Abstract:
                                                                               
The gauge/gravity duality has opened the gates to enter strongly
coupled regimes of thermal field theories and their hydrodynamic
properties. Motivated by possible application to heavy-ion collision
experiments and comparison to lattice data, spectral functions and
the phase diagrams of these theories are currently explored.
        First, I will give a short introduction to the concepts and methods
of holographic hydrodynamics. I will then present our results on
baryonic and isospin diffusion in large N gauge theory. In presence
of a background gauge field (dual to finite baryon/isospin density),
spectral functions of vector modes on probe D7-branes are considered
in an AdS Schwarzschild black hole background. Quasiparticles are
observed which correspond to vector mesons, having survived the
deconfinement transition. Features of the spectrum and diffusion
coefficient are related to the phase diagram of fundamental matter.

Title: Viscous Relativistic Hydrodynamics
                                                                               
Abstract:
It is well known that ideal fluid dynamics is able to describe the
collective flow patterns in central Au+Au collisions at high RHIC
energies.  However, this description breaks down for peripheral
collisions or for collisions at lower energies.  It is hoped that
dissipative hydrodynamics could be used to exlain this data and
extract values of transport coefficients from the QGP.  In this talk
a set of equations is formulated and implemented numerically in order
to perform causal dissipative hydrodynamic simulations of heavy-ion
collisions using the second-order GENERIC structure.  Assuming
longitudinal boost-invariance with arbitrary transverse expansion
both the azimuthally symmetric 1+1 dimensional and 1+2 dimension
cases are discussed.  The viscous corrections to the anisotropic
transverse flow and transverse momentum spectra are shown.

Title: "Phases of QCD: lattice thermodynamics, quasiparticles and
Polyakov loop"
                                                                               
Abstract:

"QCD thermodynamics is investigated by means of the
 Polyakov-loop-extended Nambu Jona-Lasinio (PNJL) model,
 in which quarks couple simultaneously to the chiral
 condensate and to a background temporal gauge field
representing Polyakov loop dynamics. The behaviour of
the Polyakov loop as a function of temperature is
obtained by minimizing the thermodynamic potential of the
 system. A Taylor series expansion of the pressure is
performed. Pressure difference and quark number density
 are then evaluated up to sixth order in quark chemical
 potential, and compared to the corresponding lattice data.
 The validity of the Taylor expansion is discussed within
 our model, through a comparison between the full results
 and the truncated ones.

"Coulomb problem for vector particles in QED and gauge theories:is the renormalizability enough?"

Abstract:                                                                              

The Coulomb problem for W-bosons (spin S=1) incorporates a well known
difficulty; the charge of the boson localized in a close vicinity of the
attractive Coulomb center proves to be infinite. The vector boson falls on
the Coulomb center. The phenomenon was discovered in the works of
Tamm, Schwinger, Oppenheimer and others 66 years ago, and since then was a
nuisance for the theory.
                                                                               
The paradox is shown to be resolved by the QED vacuum polarization, which
brings in a strong effective repulsion at very small distances
  that eradicates the infinite charge of the boson on the Coulomb center.
  This property allows one to define the Coulomb problem for vector bosons
  properly.

 It is interesting that the vacuum polarization for scalar and spinor
  particles produces only a weak effect while for vector bosons the
  situation is completely different, it produces the impenetrable potential
barrier ~1/r^4. Physical origin of this unexpected effect and its relation
  to the renormalizability of the QED and the Standard Model will be discussed.
  The renormalizability may be not enough for consistent solution of the
  non-perturbative problem.

'Thermodynamics of large N_f QCD at finite chemical potential for weak and strong couplings '
Abstract:
Resummation schemes for the entropy of hot QCD can drastically improve the poor convergence properties of strict perturbation theory. We test the non-perturbative Phi-derivable two-loop approximation, which resums the physics of hard thermal loops (HTL), in the limit of large flavor number (N_f) where the entropy and the pressure can be calculated exactly for a wide range of couplings. The exact result for the entropy is remarkably well reproduced by the HTL resummed theory for a natural choice of the renormalization scale, and this up to large values of the coupling.
