Non-local hydrodynamic transport and collective excitations in Dirac fluids
Egor I. Kiselev, Joerg Schmalian
We study the response of a Dirac fluid to electric fields and thermal gradients at finite wave-numbers and frequencies in the hydrodynamic regime. We find that non-local transport…
Lévy flights and hydrodynamic superdiffusion on the Dirac cone of Graphene
Egor I. Kiselev, Jörg Schmalian
We show that hydrodynamic collision processes of graphene at the neutrality point can be described in terms of a Fokker-Planck equation with fractional derivative, corresponding to…
Two-tone spectroscopy of a SQUID metamaterial in the nonlinear regime
E. I. Kiselev, A. S. Averkin, M. V. Fistul +2
Compact microwave resonantors made of superconducting rings containing Josephson junctions (SQUIDs) are attractive candidates for building frequency tunable metamaterials with low…
The boundary conditions of viscous electron flow
Egor I. Kiselev, Joerg Schmalian
The sensitivity of charge, heat, or momentum transport to the sample geometry is a hallmark of viscous electron flow. Therefore, hydrodynamic electronics requires the detailed unde…
