Query: Optically induced electron spin currents in the Kretschmann
  configuration   We investigate electron spin currents induced optically via plasmonic modes
in the Kretschmann configuration. By utilising the scattering matrix formalism,
we take the plasmonic mode coupled to external laser drive into consideration
and calculate induced magnetisation in the metal. The spatial distribution of
the plasmonic mode is inherited by the induced magnetisation, which acts as
inhomogeneous effective magnetic field and causes the Stern-Gerlach effect to
drive electron spin currents in the metal. We solve spin diffusion equation
with a source term to analyse the spin current as a function of the spin
diffusion length of the metal, the frequency and the incident angle of the
external drive.
