Dynamical localization and partial-barrier localization in the Paul trap
We investigate the nature of quantum localization exhibited by the center-of-mass motion of an ion in a Paul trap interacting with a standing laser field. Depending upon system parameters and the initial location of the ion, quantum suppression of chaotic diffusion is dominated by dynamical localization or localization due to partial barriers formed of broken separatrices and cantori.
