【 摘 要 】

The dynamics of partons and hadrons in ultra-relativistic nucleus-nucleus collisions are analyzed within the Parton-Hadron-String Dynamics (PHSD) transport approach, which is based on a dynamical quasiparticle model (DQPM) for the partonic phase including a dynamical hadronization scheme while reproducing lattice QCD results in thermodynamic equilibrium for the equation-of-state as well as transport coefficients like shear and bulk viscosities, the electric conductivity or the charm diffusion coefficient of the hot QCD medium. In this contribution, we report on recent results on the charm dynamics and elliptic flow in Au+Au collisions at RHIC and Pb+Pb collisions at the LHC.
