Resonant-convergent cubic response function in the random-phase approximation with application to two-photon absorption on neon in the ultraviolet-visible region
(English)Manuscript (preprint) (Other academic)
Damped cubic response functions are presented for exact-state and approximate-state methods eligible for quantum chemical computational applications. Proof of proper implementation is given, accompanied by a two-photon absorption example on neon in the ultraviolet-visible spectral region. The method accurately distinguish one- and two-photon resonances and exhibits spot-on agreement with other approaches.
