New topological properties found in 'old' material of Cobalt disulfide

Researchers have discovered the presence of Weyl nodes in bulk CoS2 that allow them to make predictions about its surface properties. The material hosts Weyl-fermions and Fermi-arc surface states within its band structure, which may enable it to serve as a platform for exotic phenomena.
