Here's the Wikipedia article on laser cooling: <a href="https://en.wikipedia.org/wiki/Laser_cooling" rel="nofollow">https://en.wikipedia.org/wiki/Laser_cooling</a><p>Its explanation is a bit too surface level for me. Anyone have more details on the mechanism used for this experiment? Would they have used Doppler cooling like is sometimes done on Rb-85?
<p><pre><code> When groups of atoms are cooled to such unfathomably low temperatures, they stop moving as individuals and meld into one big "super atom." Tens of thousands of atoms suddenly become indistinguishable from one another, slowly vibrating on a uniform wavelength that can, theoretically, pick up the tiniest gravitational disturbances around them.

Why should this be called "super atom", just because all atoms behave the same? If I have a bag of indistinguishable rice corns, they don't suddenly become a single "super rice corn".
