Abstract :
[en] We study a two-dimensional (2D) electron system with a linear spectrum in the
presence of Rashba spin-orbit (RSO) coupling in the hydrodynamic regime. We
derive a semiclassical Boltzmann equation with a collision integral due to
Coulomb interactions in the basis of the eigenstates of the system with RSO
coupling. Using the local equilibrium distribution functions, we obtain a
generalized hydrodynamic Navier-Stokes equation for electronic systems with RSO
coupling. In particular, we discuss the influence of the spin-orbit coupling on
the viscosity and the enthalpy of the system and present some of its observable
effects in hydrodynamic transport.
