"In this material, a wavelike pattern of electrons in high- and low-density regions forms spontaneously but is confined to a single direction within the material. But when hit with an ultrafast burst of laser light—less than a picosecond long, or under one trillionth of a second—that pattern, called a charge density wave or CDW, is obliterated, and a new CDW, at right angles to the original, pops into existence.
This new, perpendicular CDW is something that has never been observed before in this material. It exists for only a flash, disappearing within a few more picoseconds. As it disappears, the original one comes back into view, suggesting that its presence had been somehow suppressed by the new one."
My thoughts:
The first thought that comes to mind is "superposition"... The second thought that comes to mind is "possible higher-dimensional and/or phase-shifted view of the substructure of matter" (in this case, lanthanum tritelluride)... Even if neither of these things turn out to be the case, the phenomena is fascinating!
