I’m not a mathematician, but Emi Yukawa and Kae Nemoto from the National Institution of Informatics in Japan certainly are. Their latest work in JPhysA studies squeezing — not physical squeezing, but a mathematical treatment of squeezing in a collective SU(2J+1) system consisting of spin-J particles (J > 1/2). Our image of the week comes from visualising the roots of SU4 algebra and the following Dynkin diagrams.
I must admit its a bit too much for me, but if you have a penchant for mathematics you can head over to JPhysA and read all about it here:
