Hydrodynamic Approach to Electronic Transport in Graphene

The last few years have seen an explosion of interest in hydrodynamic effects in interacting electron systems in ultra‐pure materials. In this paper we briefly review the recent advances, both theoretical and experimental, in the hydrodynamic approach to electronic transport in graphene, focusing on viscous phenomena, Coulomb drag, non‐local transport measurements, and possibilities for observing nonlinear effects.
