A novel perturbative treatment of the time evolution operator of a quantum system is applied to the model describing a Raman-driven trapped ion in order to obtain a suitable “effective model”. It is shown that the associated effective Hamiltonian describes the system dynamics up to a certain transformation which may be interpreted as a “dynamical dressing” of the effective model.
Keywords: perturbation theory; time-dependent problems; Raman couplings.
