      abstract     = {By combining the first-principles concept based on the
                      density functional theory with a model vacuum potential, we
                      calculate image potential states and analogous ones in the
                      presence of an electric field applied on a nonmagnetic
                      Ag(100) surface and a magnetic Fe(110) surface. Our
                      investigations are based on the Green-function embedding
                      technique, which allows us to treat a truly semi-infinite
                      surface and whence yields a continuum of bulk states. This
                      turns out to be of crucial importance in order to
                      investigate the qualitative difference between localized
                      image or field states located in a band gap of the substrate
                      and states in resonance with bulk states present at the same
                      energies. This difference leads to remarkable changes in the
                      binding energy versus field dispersion of the states.
                      Furthermore, we show that in the case of the Fe(110)
                      surface, the calculated magnetic exchange splitting
                      increases with the electric field and is also modified by
                      the transition from field states to surface resonance
                      states.},
