摘要Recently, Gardas and Dajka (2013 J. Phys. A: Math. Theor. 46 235301) proposed a theoretical scheme on how to prepare a proper initial state of a composite qubit-boson system which could assure no energy exchange between the two subsystems. For illustration, they applied the proposed scheme to both the Jaynes-Cummings model and the multi-photon Rabi model. However, it has already been rigorously proven that the k-photon Rabi model for k > 2 does not have eigenstates in the Hilbert space spanned by the eigenstates of the corresponding k-photon Jaynes-Cummings model and that the two-photon Rabi model has a discrete eigenenergy spectrum with normalizable eigenstates only if the coupling strength is smaller than a critical value. Hence, the proposed theoretical scheme is not applicable to the multi-photon Rabi model.
