Explore thermalization in quantum chromodynamics through this 34-minute conference talk from the 2021 Non-Equilibrium Universality in Many-Body Physics KITP Conference. Delve into ab initio approaches and interdisciplinary connections as Raju Venugopalan discusses universal phenomena, the effectiveness of hydrodynamics, and quantum fluctuations. Examine classical equations, momentum, and cold atom experiments while learning about thermalization in heavy iron collisions. Gain insights into the chiral magnetic effect and participate in a Q&A session to deepen your understanding of non-equilibrium many-body physics at the intersection of statistical physics, AMO, condensed matter, and high-energy physics.
