Subject: Hierarchy of Information Scrambling, Thermalization, and Hydrodynamic Flow in Graphene

We determine the information scrambling rate due to electron-electron Coulomb interaction in graphene. The scrambling rate characterizes the growth of chaos and has been argued to give information about the thermalization and hydrodynamic transport coefficients of a many-body system. We discuss the scrambling rate at strong coupling, using a direct diagrammatic analysis and holographic methods and show that scrambling behaves similar to transport and energy relaxation rates. A weak coupling analysis, however, reveals that scrambling is in fact related to dephasing and single particle relaxation. Thus, while scrambling is obviously necessary for thermalization and quantum transport, it does generically not set the time scale for these processes.
