Atomic spins set quantum fluid in motion

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a quantum fluid by researchers at Science Tokyo.

The study, published in Volume 391, Issue 6783 of the journal Science on January 22, 2026, was led by Professor Mikio Kozuma, Specially Appointed Assistant Professor Hiroki Matsui, and Specially Appointed Assistant Professor Yuki Miyazawa of the Institute of Integrated Research, Science Tokyo, in collaboration with Professor Yuki Kawaguchi from the Department of Applied Physics, Nagoya University, Japan, and Professor Masahito Ueda from the Department of Physics, The University of Tokyo, Japan.
