The method for treating finite electric fields within periodic boundary conditions is used to formally define a density functional depending on the electric field. An exchange and correlation energy functional depending on the electric field is introduced and related to the functional at zero field by a formal expansion with respect to the field. © 2004 Wiley Periodicals, Inc.
