- 요약It is well known that quasiperiodicity in the Aubry-Andre-Harper (AAH) model produces ´ a localized phase of the system when the on-site potential term is sufficiently large. It is also the generic experience of an experimentalist that externally applied time-periodic potentials will add energy to a quantum system, resulting in heating. However, contrary to this intuition, dynamic localization occurs in lattice potentials of particles exposed to a time-periodic force of appropriate amplitude. The drive in this case reduces the rate of spreading and at certain amplitudes arrests the spread of the particles entirely. This is well established theoretically and has been observed experimentally.In this thesis, we present results of experimental and theoretical investigation into the effects of a number of dynamic generalizations of the AAH model. We explore the effect of applying a time-periodic external potential (chapter 5), as well as the effect of making the potential term in the AAH model periodically pulsed, referred to as the kicked AAH model (chapter 4), and the effect of periodically translating the potential in the AAH model relative to the underlying tight-binding lattice in two different frequency regimes (chapter 4). We describe the not obvious consequences of this incorporation of dynamics into experimental systems of ultracold atoms in quasiperiodic potentials.
