Description

Our goal is to build awareness in graduate students and postdoctoral researchers around the broad research opportunities in heavy-ion physics and quark-matter studies. To achieve this goal, we have invited leading members of the community to deliver talks on trending topics in the field. The workshop also includes a limited number of short talks by graduate students and early-career researchers.

        Constraining early time dynamics in ultrarelativistic Heavy Ion Collisions 30m

        It is frequently supposed that quark-gluon plasma created in heavy-ion collisions undergoes free streaming at early times. We examine this issue based on the assumption that a universal attractor dominates the dynamics already at the earliest stages, which offers a way to connect the initial state with the start of the hydrodynamic expansion in an approximate but conceptually transparent fashion. We demonstrate that the centrality dependence of the measured particle multiplicities can be used to quantitatively constrain the pressure anisotropy and find that it strongly depends on the model of the initial energy deposition. As an illustration, we compare three initial state models and show that they predict rather different early-time values of the pressure anisotropy. This strongly suggests that assuming free streaming prior to hydrodynamization is not necessarily compatible with a generic initial state model and that features of the pre-hydrodynamic flow need to be matched with the model of the initial state.

        General-relativistic viscous fluids 45m

        The discovery of the quark-gluon plasma that forms in heavy-ion collision experiments provides a unique opportunity to study the properties of matter under extreme conditions, as the quark-gluon plasma is the hottest, smallest, and densest fluid known to humanity. Studying the quark-gluon plasma also provides a window into the earliest moments of the universe, since microseconds after the Big Bang the universe was filled with matter in the form of the quark-gluon plasma. For more than two decades, the community has intensely studied the quark-gluon plasma with the help of a rich interaction between experiments, theory, phenomenology, and numerical simulations. From these investigations, a coherent picture has emerged, indicating that the quark-gluon plasma behaves essentially like a relativistic liquid with viscosity. More recently, state-of-the-art numerical relativity simulations strongly suggested that viscous and dissipative effects can also have non-negligible effects on gravitational waves produced by binary neutron star mergers. But despite the importance of viscous effects for the study of such systems, a robust and comprehensive theory of relativistic fluids with viscosity is still lacking. This is due, in part, to difficulties to preserve causality upon the inclusion of viscous and dissipative effects into theories of relativistic fluids. In this talk, we will survey the history of the problem and report on a new approach to relativistic viscous fluids that solves decade-long questions in the field, paving the way for the systematic investigation of dissipative phenomena in general relativity.

        Is hydrodynamic stability enough? 30m

        It is well known that relativistic hydrodynamic theories, to be "realistic", should be causal and stable. But stable with respect to what? The standard notion of stability one typically refers to is hydrodynamic stability, namely the requirement that on-shell perturbations away from the state of thermodynamic equilibrium remain bounded over time. I will argue that such a stability criterion is not enough to have a complete picture of the reliability of a theory and that there is a more fundamental stability principle, which relativistic fluid theories should obey.
