QCD probed by magnetic fields and boundary conditions

Falk Bruckmann (Universität Regensburg)

QCD and its phase transitions play an important role in heavy ion collisions, neutron stars and the early universe. Recently there has been a growing interest in the effects of strong (electro-)magnetic fields present in these systems. I will present new results about the influence of magnetic fields on the quark condensate and the critical temperature, obtained from lattice simulations at physical quark masses. In the second part I will discuss generalised quark boundary conditions leading to dressed Polyakov loops, which are novel order parameters for the finite temperature transition.
