Unified approach to the nonlinear Rabi models
An analytical approach is proposed to study the two-photon, two-mode and intensity-dependent Rabi models. By virtue of the su(1, 1) Lie algebra, all of them can be unified to the same Hamiltonian with ${\mathcal{Z}}_{2}$ symmetry. There exist exact isolated solutions, which are located at the level...
