Topological Hopf and chain link semimetal states and their application to Co2MnGa (Theory and Materials Prediction)

Guoqing Chang, Su-Yang Xu, Xiaoting Zhou +9

Topological semimetals can be classified by the connectivity and dimensionality of the band cross- ing in momentum space. The band crossings of a Dirac, Weyl, or an unconventional…
