Strong Light-Matter Interaction and Its Applications in Nonlinear and Quantum Optics

The ability to achieve strong interaction between light and matter now offer new ways to study and manipulate their chemical and physical properties. A particularly common approach is to use photonic environments such as high-Q optical cavities or nanoplasmonic structures to enhance the interaction of matter with quantized electromagnetic modes [1]. The ensuing effect is the hybridization of the matter system with the photon degrees which can be used to manipulate material properties [2, 3]. In this work, we present effects of strong light-matter coupling that allow to control nonlinear optical properties such as nonlinear optical susceptibility which has applications in modifying harmonic generation of fields. In another example, we look at aspects of input-output theory that describe relaxations of an ensemble of molecules coupled to the photon bath.<br/>[1] R. J. Thompson, G. Rempe, H. J. Kimble, Phys.
