Squeezing of atoms in a pulsed optical lattice
ABSTRACT Recently, we have proposed an aperiodic kicked-rotor excitation strategy leading to unlimited angular squeezing of rotational wave packets. It has been pointed out that this approach should be useful in several contexts, but it is in the setting of a pulsed optical lattice that we discuss in the present paper. We consider both classical and quantum regimes of preparing ultra-narrow (squeezed) atomic spatial distribution by a proper sequence of laser pulses forming the optical lattice. It is shown that after a linear focusing phenomenon caused by a single pulse, the rainbow-like structures appear in atomic spatial density.
