Date & Time

This workshop will bring together a select group of experimentalists and theorists to address open questions and new challenges raised by the prospect of embedding materials and molecules in high finesse optical cavities:  how can strong light-matter coupling change energy landscapes and chemical reactivities, drive the creation of new topological states of matter or control and reveal new non-equilibrium physics and what new non-equilibrium tools can/should we develop or improve to address these new scientific challenges?
