Query: Ab-initio theory of metal-insulator interfaces in a finite electric
  field   We present a novel technique for calculating the dielectric response of
metal/insulator heterostructures. This scheme allows, for the first time, the
fully first-principles calculation of the microscopic properties of thin-film
capacitors at finite bias potential. The method can be readily applied to pure
insulators, where it provides an interesting alternative to conventional
finite-field techniques based on the Berry-phase formalism. We demonstrate the
effectiveness of our method by performing comprehensive numerical tests on a
model Ag/MgO/Ag heterostructure.
