Hidden-symmetry-protected Z_2 topological insulator in a cubic lattice
Jing-Min Hou, Wei Chen
Usually topological insulators are protected by time reversal symmetry. Here, we present a new type of topological insulators in a cubic lattice which is protected by a…

Hidden antiunitary symmetry behind "accidental" degeneracy and its protection of degeneracy
Jing-Min Hou, Wei Chen
In quantum mechanics, accidental degeneracy refers to energy degeneracy that occurs coincidentally, without any protection by symmetry. Here, we prove a theorem stating that any tw…

Topological semimetals with double-helix nodal link
Wei Chen, Hai-Zhou Lu, Jing-Min Hou
Topological nodal line semimetals are characterized by the crossing of the conduction and valence bands along one or more closed loops in the Brillouin zone. Usually, these loops a…
