Acausality-driven instabilities in transient relativistic viscous hydrodynamics
Lorenzo Gavassino, Henry Hirvonen, Jean-François Paquet +2
We investigate non-linear instabilities stemming from superluminal propagation of information in Israel-Stewart-like models of relativistic viscous fluid dynamics. In relativity, t…

Analytical insights into the interplay of momentum, multiplicity and the speed of sound in heavy-ion collisions
Gabriel Soares Rocha, Lorenzo Gavassino, Mayank Singh +1
We introduce a minimal model of ultracentral heavy-ion collisions to study the relation between the speed of sound of the produced plasma and the final particles' energy and multip…
