In addition to atomic systems, the associated super-radiant phase transitions should be observable in a variety of solid-state experimental systems, including the technologically important case of interacting quantum dots coupled to an optical cavity mode.8 pages, 4 figuresQuantum PhysicsMesoscale and Nanoscale Physicstext
