Abstract

Measurements of diffusion and quantum resonances are made for the atom optics kicked rotor (AOKR) with different levels of amplitude noise applied to the kicking potential. Diffusion resonances are found to be sensitive to this noise and are destroyed by moderate levels of amplitude fluctuation. However, quantum resonance peaks are found to be robust against the applied noise. The measurements of mean energy are made after just five kicks so that comparison with the analytical theory based on the work of Shepelyansky is possible. Good agreement between theory and experimental results is found.
