Abstract
We consider spectral problems related to Dicke and Jaynes-Cummings matter-radiation Hamiltonians and write the spectrum of a perturbed Dicke model (of a trapped ion interacting with the center-of-mass motion) in explicit form. We derive the dressing chain equations for non-Abelian elements and investigate them for two-state matter models. We discuss embedding of Jaynes-Tavis-Cummings models and nonrotating wave terms.
