On the hydrodynamics of (2 + 1)-dimensional strongly coupled relativistic theories in an external magnetic field
Résumé
In this paper, we review recent progress on relativistic hydrodynamics in (2 + 1) dimensions with an external magnetic field. We discuss the formalism allowing for momentum loss due to the explicit and spontaneous breaking of translation invariance by scalar operators. We also compare to some results from the gauge/gravity correspondence.
