Abstract
Radio-frequency quantum engineering of spins is based on the dressing by a non resonant electromagnetic field. Radio-frequency dressing occurs also for the motion of particles, electrons or ultracold atoms, within a periodic spatial potential. The dressing, producing a renormalisation and also a freeze of the system energy, is described by different approaches, dressed atom, magnetic resonance semiclassical treatment, continued fraction solution of the Schr\"odinger equation. A comparison between those solutions points out that the semiclassical treatment, to be denoted as the -solution, represents the most convenient tool to evaluate the tunneling renormalization of ultracold atoms.
