The coupling between electronic spin and mechanical rotation in ultracold KRb-Rb collisions was probed experimentally and rationalized theoretically. We found and explained exceptionally large spin-roration coupling!

In the theoretical-experimental collaboration between @UniWarszawski and @WeizmannScience, we show that magnetically tunable Feshbach resonances in Sr⁺ + Rb collisions survive far above the ultracold regime—defying the idea that quantum phenomena vanish at higher temperatures.
