Transport parameters of the quark-gluon plasma: flavour dependence in the quasiparticle model

It is known that the quark-gluon plasma (QGP) is well described in terms of the relativistic hydrodynamics. Therefore, along with its equation of state and phase diagram, we are also interested in the transport properties of the QGP as a fluid. During the talk, I will present recent results for the shear and bulk viscosities, as well as electrical conductivity, obtained from the relaxation time approximation to Boltzmann equation. The calculations are performed within the quasiparticle model, where dynamical quark and gluon masses depend on the running coupling, extracted from the lattice QCD data.

Quantum and classical Virasoro conformal blocks: advances in the theory, and new applications

I will review my last few years research achievements obtained in collaboration with Franco Ferrari and Artur Pietrykowski. Our research concerns the semiclassical limit of two-dimensional Conformal Field Theory and its applications. I discuss in particular: connections between the semiclassical limit with Yang-Mills theories, quantum integrable systems and moreover applications in black holes physics and holographic interpretation.
