Molecular polaritonics: Chemical Dynamics under strong Light-Matter Coupling

Chemical manifestations of strong light-matter coupling have been recently subject of intense experimental and theoretical studies. Here we review the present status of this field. Section 1 is an introduction to molecular polaritonics and to collective response aspects of light-matter interactions. Section 2 provides an overview of the key experimental observations of these effects while Section 3 describe our current theoretical understanding of the effect of strong light-matter coupling on chemical dynamics. A brief outline of applications to energy conversion processes in given in Section 4. Pending technical issues in the constructions of theoretical approach are briefly described in Section 5. The summary in Section 6 also outlines the paths ahead in this exciting endeavor.
