Density perturbations in heavy ion collisions arround the critical point — •Kerstin Paech and Adrian Dumitru — Institut für Theoretische Physik, JWG Universität Frankfurt am Main

We introduce a model for the real-time evolution of a relativistic fluid of quarks coupled to non-equilibrium dynamics of the long wavelength (classical) modes of the chiral condensate. We solve the equations of motion numerically in 3+1 space-time dimensions. Starting the evolution at high temperature in the symmetric phase, we study dynamical trajectories that either cross the line of first order phase transitions or evolve through its critical endpoint. For those cases, we study the formation of density perturbations.
