Plasmon Enhanced Two Photon Absorption: Paper & Tutorial
The DIM/QM method for modeling plasmon-enhanced photochemical properties has recently been extended to several non-linear optical properties with damped cubic response theory. A recent paper by Zhongwei Hu and Lasse Jensen discusses the methods to simulate plasmon-enhanced two-photon absorption (PETPA) and applies this to para-nitroaniline. The coupling between the molecular excitations and the plasmon, treated with classical atomistic electrodynamics is very complex in this non-linear optical regime. The DIM/QM methods can provide insight in these complex couplings, in this case plasmon enhancement of a two-photon absorption dark state.
