Causal UV completions of relativistic hydrodynamics
Robbe Brants
Relativistic hydrodynamics successfully provides an effective field theory description for the low energy regime of many out-of-equilibrium systems. On the other hand, in this pape…

Building far-from-equilibrium effective field theories using shift symmetries
Xin An, Robbe Brants, Michal P. Heller +1
Contemporary understanding of thermalization in quantum field theory stems largely from understanding properties of transient excitations of equilibria. These nonhydrodynamic excit…

New insights into the analytic structure of correlation functions via kinetic theory
Robbe Brants
The way a relativistic system approaches fluid dynamical behaviour can be understood physically through the signals that will contribute to its linear response to perturbations. Wh…
