Workshop on Materials in Quantum Cavities and Excitonic Insulators

  • Organized by
  • Antoine Georges, Ph.D.Director, Center for Computational Quantum Physics, Flatiron Institute
  • Andrew Millis, Ph.D.CCQ Co-Director, Flatiron Institute
  • Malte Roesner, Ph.D.Associate Research Scientist, CCQ, Flatiron Institute
  • Angel Rubio, Ph.D.Distinguished Research Scientist, CCQ, Flatiron Institute
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?
