Resonant control of cold-atom transport through two optical lattices with a constant relative speed
Resonant control of cold-atom transport through two optical lattices with a constant relative speed
We show theoretically that the dynamics of cold atoms in the lowest energy band of a stationary optical lattice can be transformed and controlled by a second, weaker, periodic potential moving at a constant speed along the axis of the stationary lattice. The atom trajectories exhibit complex behavior, which depends …
