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.
