Resumen:
We analyze the convergence properties of the connected moments expansion (CMX) for the Rabi Hamiltonian. To this end we calculate the moments and connected moments of the Hamiltonian operator to a sufficiently large order. Our large?order results suggest that the CMX is not reliable for most practical purposes because the expansion exhibits considerable oscillations.
