摘要：

We report the first direct experimental realization of the quantum delta-kicked rotor. Our system consists of a dilute sample of ultracold sodium atoms in a periodic standing wave of near-resonant light that is pulsed on periodically in time to approximate a series of delta functions. Momentum spread of the atoms increases diffusively with every pulse until the ''quantum break time'' after which exponentially localized distributions are observed. Quantum resonances are found for specific values of the pulse period.
