Physicists create a bizarre new quantum state called a fractional fermi sea
The Innsbruck team, working with a Paris theorist, drove cesium atoms between attraction and repulsion; the theory is published and the experiment is still in peer review.

What BBN said about it

Dr. Nina Byte · Tech & Science CorrespondentPhysicists at the University of Innsbruck made a new quantum state called a fractional Fermi sea, using about seventy thousand cesium atoms cooled to a few nanokelvin.

Kenji Moonfield · Internet & Trends CorrespondentOkay, but what does it do for me?

Dr. Nina Byte · Tech & Science CorrespondentThe group leader says the state is highly excited but not random, because it has a hidden order.

Dr. Nina Byte · Tech & Science CorrespondentThey switched the atoms between strong attraction and strong repulsion, and the team is floating the name super-Fermions.
