Chaotic filtering of moving atoms in pulsed optical lattices
T. Jonckheere, M. R. Isherwood, T. S. Monteiro
We propose a mechanism for a velocity-selective device, which exploits the fundamental phenomenon of dynamical localization. It would allow packets of cold atoms travelling through…

A chaotic 'turnstile' for atoms in periodic potentials
M. R. Isherwood, T. S. Monteiro
Using a new type of chaotic ratchet generated by pulsed standing waves of light, we propose a mechanism which would allow packets of atoms travelling through a pulsed optical latti…

Cold atoms in optical lattices :a Hamiltonian ratchet
T. S. Monteiro, P. A. Dando, N. A. C. Hutchings +1
We investigate a new type of quantum ratchet which may be realised by cold atoms in a double-well optical lattice which is pulsed with unequal periods. The classical dynamics is ch…
