The Observation of Topologically Protected Magnetic Quasiparticles

A team of researchers from Tohoku University, J-PARC, and Tokyo Tech conducted an in-depth study of magnetic quasiparticles called "triplons." The team including Kimihiko Tanaka, Nobuyuki Kurita, Haruki Sugiyama, Hidehiro Uekusa, and Hidekazu Tanaka of Tokyo Tech, conducted the study with a low-dimensional quantum magnet, Ba2CuSi2O6Cl2, using neutron inelastic scattering by AMATERAS at J-PARC. Their findings lead to the discovery of a new "topologically protected triplon edge state" in the aforementioned compound.
