Symmetry induced selective excitation of topological states in SSH waveguide arrays
Min Tang, Jiawei Wang, Sreeramulu Valligatla +10
The investigation of topological state transition in carefully designed photonic lattices is of high interest for fundamental research, as well as for applied studies such as manip…
Mixed higher-order topology: boundary non-Hermitian skin effect induced by a Floquet bulk
Hui Liu, Ion Cosma Fulga
We show that anomalous Floquet topological insulators generate intrinsic, non-Hermitian topology on their boundary. As a consequence, removing a boundary hopping from the time-evol…
Spin-split collinear antiferromagnets: a large-scale ab-initio study
Yaqian Guo, Hui Liu, Oleg Janson +3
It was recently discovered that, depending on their symmetries, collinear antiferromagnets can actually break the spin degeneracy in momentum space, even in the absence of spin-orb…
Engineering a pure Dirac regime in ZrTe
Jorge I. Facio, Elisabetta Nocerino, Ion Cosma Fulga +13
Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets. This tends to mask the physics of the relativistic quasiparticles.…
Disorder effects on triple-point fermions
Hsiu-Chuan Hsu, Ion Cosma Fulga, Jhih-Shih You
The stability of three-dimensional relativistic semimetals to disorder has recently attracted great attention, but the effect of disorder remains elusive for multifold fermions, th…
Magnetic warping in topological insulators
Gabriele Naselli, Ali G. Moghaddam, Solange Di Napoli +4
We analyze the electronic structure of topological surface states in the family of magnetic topological insulators MnBiTe. We show that, at natural-cleavage surface…
