We show that phase noise can induce nontrivial dynamics in atoms prepared in a superposition of momentum eigenstates of a periodic potential. Experimental measurements demonstrate a resonance in mean energy as a function of the size of applied random phase jumps. We discuss the mechanism for the observed behavior and show that it could also lead to noise-induced divergence between quantum and classical dynamics.
