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 of excited-state quantum phase transitions demarcating the upper edge of the superradiant phase. For the Dicke model,...
