Title: Carrollian origins of Bjorken flow

Abstract: Bjorken flow describes the motion of the highly energetic state of matter produced in heavy ion collisions as an ultra-relativistic fluid. It is among the simplest phenomenological models of fluids moving at speeds very close to the speed of light. We know that fluids moving at the speed of light are restricted to move on null surfaces. On the other hand, Carroll symmetries arise on generic null surfaces and Carroll fluids describe fluids moving on a null manifold. Thus, it seems very natural that the Bjorken flow and the associated phenomenological approximations should be completely captured by Carroll fluids. In this talk, we will show that this is indeed the case, and thereby demonstrate that Carrollian hydrodynamics is quite ubiquitous, and provides a concrete framework for fluids moving at speeds close to the speed of light.
