Abstract
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 ‘ef fective model’. It is shown that the associated ef fective Hamiltonian describes the system dynamics up to a certain transformation which may be interpreted as a ‘dynamical dressing’ of the ef fective model
