Description
I will discuss the method we have developed over the last years to correctly describe strong light-matter coupling in arbitrary nanophotonic structures. This method obtains a quantum-optics-like description using a few discrete modes while still accounting for the full complexity of light propagation and emission. As a natural consequence, this method yields quantum optical models consisting of coupled lossy modes with strong non-Hermitian character, which can enable novel applications and protocols in quantum optics. I will then discuss how these ideas can be extended to directly access photon correlations of the emitted light resolved in space, frequency, time and polarization. Finally, I will show how to integrate the method with molecular descriptions based on QM/MM models, and how using it to describe emitter arrays coupled to periodic light modes can give polaritons with unprecedented nonlinear response.
