In this talk I shall discuss the S-matrix formulation of statistical mechanics, which connects the scattering matrix elements to the thermodynamic observables. The approach allows a consistent treatment of broad resonances and purely repulsive channels, while correctly implementing the constraints from the chiral perturbation theory. This provides a useful framework for identifying the...

A review of interrelation between those two fields consistes of two parts. One covers recent progress in ``magnetic scenario", which treats QGP as a dual plasma containing as quasiparticles not only quarks and gluons but also magnetic monopoles, dominating the ensamble near $T_c$. Recent account for monopoles contribution to jet quenching has solved the problem with azimuthal...

We describe a numerical method which allows to go beyond the classical approximation for the real-time dynamics of many-body systems by approximating the many-body Wigner function by the most general Gaussian function with time-dependent mean and dispersion. On a simple example of a classically chaotic system with two degrees of freedom we demonstrate that the Gaussian state approximation is...
