Velocimetry of cold atoms by matterwave interferometry.
We present a method for the velocimetry of cold atoms by matterwave interferometry, which we have used to measure the velocity distributions within freely-expanding clouds of $^{85}$Rb atoms at temperatures of 17 and 33 $\mu$K. Quadrature measurement using an asymmetric three-pulse technique allows determination of the full analytic interferometer signal which yields the 1-D velocity distribution with excellent fidelity. The technique is particularly suited to ultracold samples, and avoids some of the artefacts of conventional Doppler and time-of-flight methods.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
