Query: Linking boundary conditions for kinetic and hydrodynamic description of
  fermion gas   An approximate analytical solution of the boundary slip problem in magnetic
field is obtained by using the general form of boundary conditions for the
distribution function of fermions with the isotropic energy spectrum. Exact
numerical calculations of the slip length for different models of
angle-dependent specularity parameter and application of the results to the
description of the Poiseuille flow demonstrate the reliability of the
approximate solution for establishing a direct link between the hydrodynamic
and the kinetic approaches to transport in bounded fermion systems.
