Hot QCD matter in the influence of electromagnetic fields

Strong magnetic fields are expected to be generated in the very early stages of non-central asymmetric collisions at the RHIC and LHC. However, a proper theoretical model for the magnetic field evolution in the nuclear medium is yet to be known. The decay of the magnetic field may depend on the medium properties, say electromagnetic responses (conductivity) of the medium. The charged fermions follow 1+1−dimensional Landau level kinematics in the presence of strong magnetic fields, and this, in turn, violates the rotational symmetry of the system. On the other hand, in a weakly magnetized medium, the temperature remains as the dominant energy scale of the medium (in comparison with the magnetic field). In this talk, we will discuss certain interesting aspects of the transport properties of the magnetized QCD medium both in the strong and weak field regimes. Another focus of the talk is on heavy quark dynamics in an expanding and in magnetized medium.
