Anew study provides the first evidence of exotic particles, known as fourfold topological quasiparticles, in the metallic alloy cobalt monosilicide. Published in the Proceedings of the National Academy of Sciences, this comprehensive analysis, one that combines experimental data with theoretical models, provides a detailed understanding of this material. These insights could be used to engineer this and other similar materials with unique and controllable properties. The discovery was the result of a collaboration between researchers at Penn, University of Fribourg, French National Center for Scientific Research (CNRS), Max Planck Institute for Chemical Physics of Solids, and University of Maryland. from Phys.org - latest science and technology news stories https://ift.tt/3kGi1BC
