Chaotic dynamics and tunneling of an atom in a magneto-optical double-potential well

Summary form only given. Dynamics associated with a particle in a double-potential well play a key role in numerous areas of pure and applied sciences, and is an important paradigm for quantum coherent evolution. Most fundamental is the decay or oscillation of a meta-stable state via quantum tunneling. We consider the dynamics of laser cooled atoms in a magneto-optical lattice of such double wells.
