Caption
An artist's impression of how the team identified this historic phase of matter. The researchers used x-rays to measure how spins (blue arrows) move when they are disturbed and were able to show that they oscillate in length in the pattern illustrated above. This special behavior occurs because the amount of electrical charge at each site (shown as yellow disks) can also vary and is the fingerprint used to pin down the novel behavior.
