AB We study critical behavior of excited states and its relation to order and chaos in the Jaynes-Cummings and Dicke models of quantum optics. We show that both models exhibit a chain ofexcited-state quantum phase transitions demarcating the upper edge of the superradiant phase. Forthe Dicke model, the signatures of criticality in excited states are blurred by the onset of chaoswhich happens in the same energy region.
