Very cool! Why these atoms? Why pick chromium?

We have openings for theory and experimental students. Topics include: quantum sensing, ultracold polar molecules, 3D atomic arrays for quantum computing, Rydberg quantum optics and vector light.

Hi, could I be added please? scholar.google.com/citations?us...

Hi, I’m Liam, a physicist at Durham University in the UK working on photonics and quantum optics. Could I be added to the feed?

I’ve been involved in demonstrations that make colour changing pictures using tape and polarisers. It’s very hands on and the kids love it. physics.aps.org/articles/v15...

Hi, I’m a researcher working on semiconductor quantum optics and microwave-optical conversion. Could I be added to the feed please?

The cooling works in a similar way to a conventional fridge (expansion of gas). The difference is we use helium, which has the lowest boiling point of any gas. To get to temperatures below 1 K we use helium-3, a rare isotope with an even lower boiling point.

MilliKelvin. 300 mK is 0.3 degrees above absolute zero, so pretty cold!

All good science relies on tin foil!
