Universality of sound modes in kinetic theory
Xiaojian Du, Stephan Ochsenfeld, Sören Schlichting
We present a simple approach to extract hydrodynamic sound modes and non-hydrodynamic modes in kinetic theories from response functions of the energy-momentum tensor. By comparing…
Quantum simulation of in-medium QCD jets: momentum broadening, gluon production, and entropy growth
