The non-local hydrodynamic transport properties of graphene — •Egor Kiselev¹ and Jörg Schmalian^1,2 — ¹Institut für Theorie der Kondensierten Materie, Karlsruher Institut für Technologie, 76131 Karlsruhe, Germany — ²Institut für Festkörperphysik, Karlsruher Institut für Technologie, 76131 Karlsruhe, Germany

Within a kinetic theory approach, we calculate the non-local transport properties of graphene in the hydrodynamic regime, in the limit of a small graphene fine structure constant. We find an exact solution to the kinetic equation and derive exact expressions for the non-local (i. e. finite momentum and frequency) conductivity and viscosity. Possible applications of our findings to the study of relaxation phenomena will be discussed.
