Topological Classification of Non-Hermitian Hamiltonians
Charles C. Wojcik, Xiao-Qi Sun, Tomáš Bzdušek +1
We revisit the problem of classifying topological band structures in non-Hermitian systems. Recently, a solution has been proposed, which is based on redefining the notion of energ…
Non-Abelian reciprocal braiding of Weyl points and its manifestation in
Adrien Bouhon, QuanSheng Wu, Robert-Jan Slager +3
Weyl semimetals in three-dimensional crystals provide the paradigm example of topologically protected band nodes. It is usually taken for granted that a pair of colliding Weyl poin…
Alice string in Non-Hermitian Systems
Xiao-Qi Sun, Charles C. Wojcik, Shanhui Fan +1
Alice string is a topological defect with a very peculiar feature. When a defect with a monopole charge encircles an Alice string, the monopole charge changes sign. In this work, w…
