Dance diagram for math geeks. In these two-dimensional choreographic crystals, the arrows show directions of particles, arrayed initially on a triangular lattice, that move in straight lines from blue to yellow to pink
Latham Boyle, from the Perimeter Institute for Theoretical Physics in Waterloo, Canada, first began to think the problem over while mulling over plans for a space observatory ELISA (Evolved Laser Interferometer Space Antenna) to detect gravitational waves.
The scientists admitted that they do not know whether these "dancing" crystals actually exist in nature, but suggest that the motions of atomic nuclei or electrons in solids could be coordinated in this way.
To examine this in detail, scientists can use a spate of diffraction methods, including those conducted with the help of X-ray analysis, the researchers concluded.
