The role of quasi-momentum in the resonant dynamics of the atom-optics kicked rotor
Sandro Wimberger, Mark Sadgrove
We examine the effect of the initial atomic momentum distribution on the dynamics of the atom-optical realisation of the quantum kicked rotor. The atoms are kicked by a pulsed opti…
Atom optics kicked rotor: experimental evidence for a pendulum description of the quantum resonance
S. Wayper, M. Sadgrove, W. Simpson +1
We present measurements of the mean energy for an atom optics kicked rotor ensemble close to quantum resonance. Oscillations in the mean energy in this regime are are shown to be i…
Experimental verification of a one-parameter scaling law for the quantum and "classical" resonances of the atom-optics kicked rotor
Sandro Wimberger, Mark Sadgrove, Scott Parkins +1
We present experimental measurements of the mean energy in the vicinity of the first and second quantum resonances of the atom optics kicked rotor for a number of different experim…
Quantum and Classical Effects in the Two-Frequency Kicked Rotor with Variable Initial Phase
T. G. Mullins, A. J. Hilliard, M. P. Sadgrove +3
We present an investigation into effects exhibited by the two-frequency kicked rotor. Experiments were performed and in addition quantum and classical dynamics were simulated and c…
Measurements of Diffusion Resonances for the Atom Optics Quantum Kicked Rotor
M. E. K. Williams, M. P. Sadgrove, A. J. Daley +5
We present experimental observations of diffusion resonances for the quantum kicked rotor with weak decoherence. Cold caesium atoms are subject to a pulsed standing wave of near-re…
