Abstract
We present experimental and numerical studies of the atomic motion in an op tical lattice displaying a fivefold rotational symmetry. The atomic transpo rt has been investigated by measuring the time evolution of the size of the atomic cloud. The experimental results are compared to those of a semiclas sical Monte Carlo simulation of the atomic motion in a three-dimensional op tical quasicrystal. A good agreement has been obtained on the anisotropy of the diffusive expansion of the cloud. [S1050-2947(99)50312-0].
