Poor man's derivation of the Bethe-Ansatz equations for the Dicke model
arXiv:1008.1844 · doi:10.1103/PhysRevB.82.092203
Abstract
We present an elementary derivation of the exact solution (Bethe-Ansatz equations) of the Dicke model, using only commutation relations and an informed Ansatz for the structure of its eigenstates.
