Hybrid theoretical models for molecular nanoplasmonics

The multidisciplinary nature of the research in molecular nanoplasmonics, i.e. the use of plasmonic nanostructures to enhance, control or suppress properties of molecules interacting with light, led to contributions from di erent theory communities over the years, with the aim to understand, interpret and predict the physical and chemical phenomena occurring at the molecular- and nano-scale in presence of light. Multiscale hybrid techniques, using a di erent level of description for the molecule and the plasmonic nanosystems, permit a reliable representation of the atomistic details and of collective features, like plasmons, in such complex systems. Here we focus on a selected set of topics of current interest in molecular plasmonics (control of electronic excitations in light harvesting systems, polaritonic chemistry, hot carrier generation and plasmon-enhanced catalysis). We discuss how their description may benefit from a hybrid modeling approach and what are the main challenges for the application of such models. In doing so, we also provide an introduction to such models and to the selected topics, as well as general discussions on their theoretical descriptions
