Raiders Of The Lost Dimension

A new state of matter - the Bose Einstein condensate (BEC) - absolutely stunning work (with some potentially stunning implications) from the folks at Los Alamos

A team of scientists working at the National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos has uncovered an intriguing phenomenon while studying magnetic waves in barium copper silicate, a 2,500-year-old pigment known as Han purple.
The researchers discovered that when they exposed newly grown crystals of the pigment to very high magnetic fields at very low temperatures, it entered a rarely observed state of matter. At the threshold of that matter state--called the quantum critical point-the waves actually lose a dimension.

That is, the magnetic waves go from a three-dimensional to a two-dimensional pattern. The discovery is yet another step toward understanding the quantum mechanics of the universe.
