Abstract

Plasmonic nanomaterials and quantum metamaterials have the unique ability to confine light in extremely sub-wavelength volumes and massively enhance electromagnetic fields. The talk will discuss the principles of room-temperature strong coupling quantum dynamics in structured environs and illuminate perspectives for nanophotonics and topological quantum metamaterials with quantum gain on the nanoscale. We will highlight recently demonstrated room-temperature strong coupling of single molecules in a plasmonic nano-cavity and near-field strong coupling of single quantum dots as well as strong coupling and exceptional points in active hyperbolic metamaterials. We will discuss the electron-beam control of plexitonic dynamics and further present a new protocol demonstrating how nanoplasmonic room-temperature strong coupling offers an innovative route towards single-molecule immunoassay sensing and dynamic quantum entanglement.
