Can order be caused by quantum zero point fluctuations? A new Proceedings of the National Academy of Sciences paperby Montu's group (Matt Coak, Seb Haines, Cheng Liu) with Stephen Rowley and Gil Lonzarich presents the most comprehensive experimental and theoretical study of order-by-disorder in a solid crystal system to date.
