If you have a question about this talk, please contact Dr Miguel Navarro-Cia. Plasmonic nanomaterials have the unique ability to confine light in extremely sub-wavelength volumes and massively enhance electromagnetic fields. With sufficient field enhancement, one enters the strong- coupling regime, where the energy exchange between the excited states of molecules/materials and plasmons is faster than the de-coherence processes of the system. As a result, the excitonic state of the molecule becomes entangled with the photonic mode, forming hybrid excitonic-photonic states. These hybrid-states are part light, part matter and allow for characteristic Rabi oscillations of the atomic excitations to be observed. Until recently, the conditions for achieving such strong-coupling were most commonly met at cryogenic temperatures such that de-coherence processes are suppressed. As a major step forward, we have recently demonstrated room-temperature strong coupling of single emitters1 to ultra-confined light fields in plasmonic resonators2 at ambient conditions which is of immense interest for a practical implementation of nanophotonic quantum quantum technologies at room temperature. In the talk I shall illuminate the horizons for active nanophotonics, discussing recently demonstrated room- temperature strong coupling of single molecules in a plasmonic nano-cavity1 and near-field strong coupling of single quantum dots2 as well as strong coupling and exceptional points in active hyperbolic metamaterials3 and chart an outline how nanoplasmonic room-temperature strong coupling provides a route to an innovative route towards single-molecule immunoassay sensing. Embracing topological metamaterials4 with quantum gain on the nanoscale I shall also shed light on the potential of (quantum-) metamaterials5 and show how quantum chaos is enabling control of nonlinear spatio-temporal chaos6.
