Query: $GW$ self-screening error and its correction using a local density
  functional   The self-screening error in electronic structure theory is the part of the
self-interaction error that would remain within the $GW$ approximation if the
exact dynamically screened Coulomb interaction, $W$, were used, causing each
electron to artificially screen its own presence. This introduces error into
the electron density and ionization potential. We propose a simple,
computationally efficient correction to $GW$ calculations in the form of a
local density functional, obtained using a series of finite training systems;
in tests, this eliminates the self-screening errors in the electron density and
ionization potential.
