Resonance Lifetimes from Complex Densities

ORAL

Abstract

The \emph{ab-initio} calculation of resonance lifetimes of metastable anions challenges modern quantum-chemical methods. The exact lifetime of the lowest-energy resonance is encoded into a complex ``density'' that can be obtained via complex-coordinate scaling. Using one and two electron examples, we illustrate a method for extracting the lifetime from the complex density and explore a Kohn-Sham analog for resonances.
