Abstract

The measurements of early-time momentum diffusion for the atom-optical delta-kicked rotor (DKR) were analyzed. The Bose-Einstein condensate provided a source of ultracold atoms with an ultranarrow initial momentum distribution which was then subjected to periodic pulses using an intense far-detuned optical standing wave. The effects of varying the effective Planck's constant for the system were also analyzed. It was found that the observed behavior includes quantum resonances (ballistic energy growth) and antiresonances (re-establishment of the initial state).
