    "abstract": "A novel expansion of the evolution operator associated with a -- in general,\ntime-dependent -- perturbed quantum Hamiltonian is presented. It is shown that\nit has a wide range of possible realizations that can be fitted according to\ncomputational convenience or to satisfy specific requirements. As a remarkable\nexample, the quantum Hamiltonian describing a laser-driven trapped ion is\nstudied in detail.",
