Query: Van Hove scenario of anisotropic transport in a two-dimensional
  spin-orbit coupled electron gas in an in-plane magnetic field   We study electronic transport in two-dimensional spin-orbit coupled electron
gas subjected to an in-plane magnetic field. The interplay of the spin-orbit
interaction and the magnetic field leads to the Van Hove singularity of the
density of states and strong anisotropy of Fermi contours. We develop a method
that allows one to exactly calculate the nonequilibrium distribution function
for these conditions within the framework of the semiclassical Boltzmann
equation without using the scattering time approximation. The method is applied
to calculate the conductivity tensor and the tensor of spin polarization
induced by the electric field (Aronov-Lyanda-Geller-Edelstein effect). It is
found that both the conductivity and the spin polarization have a sharp
singularity as functions of the Fermi level or magnetic field, which occurs
when the Fermi level passes through the Van Hove singularity. In addition, the
transport anisotropy dramatically changes near the singularity.
