We provide numerical evidence that a Kelvin-Helmholtz instability occurs in the Dirac fluid of electrons in graphene and can be detected in current experiments. This instability appears for electrons in the viscous regime passing though a micrometer-scale obstacle and affects measurements on the time scale of nanoseconds. A possible realization with a needle-shaped obstacle is proposed to produce and detect this instability by measuring the electric potential difference between contact points… 
Effects of dissipation on solitons in the hydrodynamic regime of graphene
We use hydrodynamic techniques to analyze the one-dimensional propagation of solitons in gated graphene on an arbitrary uniform background current. Results are derived for both the Fermi liquid and
Perturbation theory for two-dimensional hydrodynamic plasmons
Direct current in confined two-dimensional (2d) electron systems can become unstable with respect to the excitation of plasmons. Numerous experiments and simulations hint that structural asymmetry
Nonequilibrium and morphological characterizations of Kelvin–Helmholtz instability in compressible flows
We investigate the effects of viscosity and heat conduction on the onset and growth of Kelvin–Helmholtz instability (KHI) via an efficient discrete Boltzmann model. Technically, two effective

Transport coefficients in ultrarelativistic kinetic theory
A spatially-periodic longitudinal wave is considered in relativistic dissipative hydrodynamics. At sufficiently small wave amplitudes, an analytic solution is obtained in the linearised limit of the
High-order quadrature-based lattice Boltzmann models for the flow of ultrarelativistic rarefied gases
We present a systematic procedure for the construction of relativistic lattice Boltzmann models (R-SLB) appropriate for the simulation of flows of massless particles. Quadrature rules are used for
Kinetic Simulation of Nonequilibrium Kelvin-Helmholtz Instability
The recently developed discrete Boltzmann method (DBM), which is based on a set of uniform linear evolution equations and has high parallel efficiency, is employed to investigate the dynamic
Active nematic-isotropic interfaces in channels.
An improved hybrid model of finite differences and the lattice Boltzmann method with a multi-relaxation-time collision operator is used, the accuracy of which allowed us to characterize the dynamics of the distinct interfacial regimes.
