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…
Contribution of forbidden orbits in the photoabsorption spectra of atoms and molecules in a magnetic field
A. Matzkin, P. A. Dando, T. S. Monteiro
In a previous work [Phys. Rev. A \textbf{66}, 0134XX (2002)] we noted a partial disagreement between quantum R-matrix and semiclassical calculations of photoabsorption spectra of m…
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…
