New framework links magnetic phase boundaries to string-like defects in spin ice‎

A research team led by Haruki Watanabe, a professor in the Department of Physics and the Jockey Club Institute for Advanced Study (IAS) at The Hong Kong University of Science and Technology (HKUST), in collaboration with professor Yukitoshi Motome and graduate student Sena Watanabe from the University of Tokyo, has developed a unified theory that predicts when two states of matter are genuinely distinct and when they are actually the same.
