G. Vignale, Walter Kohn
The frequency-dependent exchange-correlation potential, which appears in the usual Kohn-Sham formulation of a time-dependent linear response problem, is a strongly nonlocal functio…

Surface Effects on Bulk Plasmons
Olle Heinonen, Walter Kohn
We discuss the effects of surfaces on bulk plasma oscillations in a metallic film of thickness . The leading corrections to the plasma frequencies due to the surfaces are propor…
