Geometric approach to fragile topology beyond symmetry indicators
Adrien Bouhon, Tomáš Bzdušek, Robert-Jan Slager
We present a framework to systematically address topological phases when finer partitionings of bands are taken into account, rather than only considering the two subspaces spanned…
Non-abelian topology of nodal-line rings in -symmetric systems
Apoorv Tiwari, Tomáš Bzdušek
Nodal lines inside the momentum space of three-dimensional crystalline solids are topologically stabilized by a -flux of Berry phase. Nodal-line rings in -symmetri…
Non-Abelian band topology in noninteracting metals
QuanSheng Wu, Alexey A. Soluyanov, Tomáš Bzdušek
Electron energy bands of crystalline solids generically exhibit degeneracies called band-structure nodes. Here, we introduce non-Abelian topological charges that characterize line…
Three-dimensional Chiral Lattice Fermion in Floquet Systems
Xiao-Qi Sun, Meng Xiao, Tomáš Bzdušek +2
We show that the Nielsen-Ninomiya no-go theorem still holds on Floquet lattice: there is an equal number of right-handed and left-handed Weyl points in 3D Floquet lattice. However,…
Conversion rules for Weyl points and nodal lines in topological media
Xiao-Qi Sun, Shou-Cheng Zhang, Tomáš Bzdušek
According to a widely-held paradigm, a pair of Weyl points with opposite chirality mutually annihilate when brought together. In contrast, we show that such a process is strictly f…
