Abstract
We investigate the behavior of large eigenvalues for the quantum Rabi Hamiltonian, i.e., for the Jaynes–Cummings model without the rotating wave approximation. The three-term asymptotics we obtain involves all the parameters of the model so that we can recover them from the behavior of its large eigenvalues.
