Title: High Density Matter Out of Equilibrium: From the Lab to the Sky

Abstract: In this seminar I will discuss some of the main challenges concerning the description of quantum chromodynamics (QCD) in the baryon rich regime in heavy ion collisions and also in neutron star mergers. After presenting a realistic prediction for the location of the critical point in the QCD phase diagram, I will present the first systematic study of the emergence of hydrodynamics in a far-from-equilibrium relativistic fluid with a critical point. For rapidly expanding systems such as the matter formed in heavy ion collisions, the onset of hydrodynamic behavior is shown to be significantly delayed by the presence of critical phenomena. We then switch gears to consider the out-of-equilibrium behavior of the extremely dense matter formed in neutron star mergers. We solved a long standing open problem in the field of viscous hydrodynamics and its coupling to general relativity by proving causality, existence, and uniqueness of the solutions of the highly nonlinear equations of motion of viscous hydrodynamics in curved spacetime. These results pave the way for the inclusion of viscous effects in state-of-the-art simulations of gravitational-wave signals coming from neutron star mergers.
