The Quantum Kicked Rotor
The quantum kicked rotor has served as a model for testing the ideas of quantum chaos since the field's inception. In this thesis we present an overview of the kicked rotor, both from a semiclassical standpoint as well as from a purely quantum standpoint. At the heart of our kicked rotor model is a …

Chaos and Momentum Diffusion of the Classical and Quantum Kicked Rotor
… in a manner similar to classical chaos. For the kicked rotor, which is a bounded system, we use the Benettin et al. method to calculate both classical and quantum Lyapunov exponents as a function of control parameter K and find chaos in both cases. Within the chaotic sea we find in both cases …

Chaos and Localisation
… hydrogen atoms subject to a microwave field, and kicked atoms which mimic the delta-kicked rotor model. Both of these systems show a complex dynamical evolution arising from the interaction with an external time-periodic driving force. In particular two quantum phenomena, which have no counterpart …

Novel Aspects of Localization, Delocalization, and Anomalous Transport in One-dimensional Systems
… periodically driven system, the relativistic kicked-rotor. We investigate disorder effects in our driven system and find that its natural yet special configurations of disorder leads to superballistic transport in the momentum space.

Quantum Transport Experiments with Ultracold Atoms
… the quantum chaotic system of the deltakicked rotor, and a spatially disordered potential. The delta-kicked rotor investigations focus on the effects of phase modulation. By applying a periodic phase modulation of f0; 2 =3; 0g, the phase space is modified to generate a Hamiltonian …
