Light-shift spectroscopy of optically trapped atomic ensembles
Ashby P. Hilton, Andre N. Luiten, Philip S. Light
We develop a method for extracting the physical parameters of interest for a dipole trapped cold atomic ensemble. This technique uses the spatially dependent ac-Stark shift of the…

Dual-colour magic-wavelength trap for suppression of light shifts in atoms
Ashby P. Hilton, Christopher Perrella, Andre N. Luiten +1
We present an optical approach to compensating for spatially varying ac-Stark shifts that appear on atomic ensembles subject to strong optical control or trapping fields. The intro…

High-efficiency cold-atom transport into a waveguide trap
Ashby P. Hilton, Christopher Perrella, Fetah Benabid +3
We have developed and characterized an atom-guiding technique that loads cold rubidium atoms into hollow-core optical fibre, an order-of-magnitude larger than previou…
