Nanoplasmonics is a new field of research emerging on the interface of atomic, molecular, and solid-state physics as well as (nano-)chemistry. Here, the interaction between metallic nanoparticles, electromagnetic fields, and an adjacent molecular system are described and evaluated.
We focus on the development of a self-consistent theoretical treatment of coupled metallic-organic hybrid materials from an electromagnetic, quantum chemical & dynamical perspective for an in-depth understanding of the dynamics of the combined hybrid system.
In this contribution we present the first results of our simulation of a coupled excitonic-plasmonic hybrid model system. Upon interaction with a time-dependent laser field, the inorganic metal model gives rise to a localised surface plasmon while a Frenkel exciton is formed on the organic molecular aggregate. The coherent temporal evolution of the coupled system is then simulated by numerically solving the time-dependent Schrödinger equation. Possible approaches towards the implementation will be discussed and the underlying approximations critically evaluated.
