Abstract
We discuss the analogy between nondispersive wave packets in periodica lly driven hydrogen atoms and solitons as solitary wave solutions of n onlinear dynamical systems. Whereas the wave packet eigenstates should not be considered as solitons propagating in real space, they are sho wn to display the essential features of solitonic solutions as they pr opagate through the irregular lattice of quasienergy levels evolving w ith a fictitious time like the strength or the frequency of the drivin g force.
