Laser cooled atoms have proven transformative for precision metrology, playing a pivotal
role in state-of-the-art clocks and interferometers and having the potential to provide a step …

The Sagnac effect enables interferometric measurements of rotation with high precision.
Using matter waves instead of light promises resolution enhancement by orders of …

We have studied the optical properties of gratings microfabricated into semiconductor
wafers, which can be used for simplifying cold-atom experiments. The study entailed the …

New counterpropagating geometries are presented for localizing ultracold atoms in the dark
regions created by the interference of Laguerre–Gaussian laser beams. In particular dark …

We report on the implementation of an optical tweezer system for controlled transport of
ultracold atoms along a narrow, static confinement channel. The tweezer system is based on …

We report an experimental realization of ultracold atoms confined in a time-averaged,
adiabatic potential (TAAP). This trapping technique involves using a slowly oscillating …

We have observed the interference between two Bose–Einstein condensates of weakly
bound Feshbach molecules of fermionic 6 Li atoms. Two condensates are prepared in a …

The role of source cloud spatial coherence in a Mach-Zehnder-type atom interferometer is
experimentally investigated. The visibility and contrast of a Bose-Einstein condensate (BEC) …

We present a three-dimensional steerable optical tweezer system based on two pairs of
acousto-optic deflectors. Radio frequency signals used to steer the optical tweezers are …

Nearly two centuries ago Talbot first observed the fascinating effect whereby light
propagating through a periodic structure generates a “carpet” of image revivals in the near …
