behavior to take over.

And that's what allows things like superconductivity to happen, superfluidity to happen, Bose-Einstein condensates to happen, and of course, Fermi gases to happen as well.

You need something to be really, really cold.

So this is why, essentially why electrons will require these really, really cold regimes in order to pair up, to form Cooper pairs and do their superconductivity bit.

So in this state, then, lithium atoms essentially act like electrons.

And it all comes down to the fact that they're fermions.

If you're fermionic, I don't need to go into detail about that.

But they essentially act like electrons.

They pair up.

They get together and do their thing.

So that makes it, when the atoms are pairing up, it makes, it turns it into a much more controllable investigation.

You know what I mean?

So if we, we can't examine electrons in this way using this ultra cold atom microscope.

We need to use these lithium atoms to make it so that it's something that we can investigate in a very controlled, accurate way.

So that's why they're using this method.

Does that make sense why the guys, they're creating this Fermi gas, ultra-cold Fermi gas using lithium atoms, and they act like electrons.

They form Cooper pairs together, and that way we can see what's going on a lot easier than if we were using electrons.

So what did they find?

After they paired up, after they formed Cooper pairs, these atoms moved in what they described as a synchronized dance.

So if you have one pair, if you're looking at one pair, one Cooper pair of atoms or electrons, the position of that pair is actually dependent on the position of other pairs.
