We present a simulation method which localizes the atomic wave function each time a spontaneous photon is emitted. This allows a small set of basis states to be allocated dynamically to follow the atomic motion. We illustrate the application of this technique in a study of position jumps and quantum diffusion in the laser cooling of atoms.
