Caption

A new kind of hourglass-shaped fermion, a subatomic particle, on the surface of a KHgSb crystal can be 'folded' by manipulating the arrangement of atoms. This material relates to a paper that appeared in the 05 May 2017, issue of Science Advances, published by AAAS. The paper, by J. Ma at Chinese Academy of Sciences in Beijing, China, and colleagues was titled, "Experimental evidence of hourglass fermion in the candidate May 2017 nonsymmorphic topological insulator KHgSb."
