Researchers at Princeton University visualized direct evidence of a Wigner crystal, confirming electrons' ability to assemble in quantum phases.

Researchers at Princeton University have visualized direct evidence of a Wigner crystal, a crystal-like formation made entirely of electrons, without the need to coalesce around atoms. This 90-year-old theory confirms electrons' ability to assemble in collective quantum phases, potentially leading to the discovery of new quantum phases of matter. The study, published in Nature, utilized a scanning tunneling microscope and two pieces of graphene for the clearest images yet.
