Hydrodynamic and Ballistic Transport of Electrons in 2d Materials

Electron transport in 2-dimensional systems with weak electron-lattice
interactions can transition from an ohmic to a ballistic or a
regime. We show the occurrence of these transitions by viewing electrons
at the kinetic level in experimentally realizable systems. We solve our
kinetic model using "bolt", a computer package we have developed for
solving the Boltzmann equation, keeping intact its full time-dependence
non-linearity. We trace the choreography of vortices produced by AC
in each of the non-ohmic regimes and define clear experimental
of ballistic and hydrodynamic behavior.
