Low-cost optical manipulation using hanging droplets of PDMS [PDF]
, 2015 We propose and demonstrate a low-cost optical micromanipulation system that makes use of simple microfrabricated components coupled to a smartphone camera for imaging. Layering hanging droplets of polydimethylsiloxane (PDMS) on microscope coverslips, and

Interference scheme to measure light-induced nonlinearities in Bose-Einstein condensates
, 2003 Light-induced nonlinear terms in the Gross-Pitaevskii equation arise from the stimulated coherent exchange of photons between two atoms. For atoms in an optical dipole trap this effect depends on the spatial profile of the trapping laser beam.
