Query: On the Reduced Hartree-Fock Equations with a Small Anderson Type
  Background Charge Distribution   We demonstrate that the reduced Hartree-Fock equation (REHF) with a small
Anderson type background charge distribution has an unique stationary solution
by explicitly computing a screening mass at positive temperature.
