Query: Measurements of Diffusion Resonances for the Atom Optics Quantum Kicked
  Rotor   We present experimental observations of diffusion resonances for the quantum
kicked rotor with weak decoherence. Cold caesium atoms are subject to a pulsed
standing wave of near-resonant light, with spontaneous emission providing
environmental coupling. The mean energy as a function of the pulse period is
determined during the late-time diffusion regime for a constant probability of
spontaneous emission per unit time. Structure in the late-time energy is seen
to increase with physical kicking strength. The observed structure is related
to Shepelyansky's predictions of the initial quantum diffusion rates.
