Rotation topological states: theory and material realization
Chun-Xue Liu, Yilin Han, Runze Li +2
The conventional characterization of topological materials relies on topological invariants calculated from the entire set of occupied bands. However, when a system possesses rotat…
Anomalous shift in scattering from topological nodal-ring semimetals
Runze Li, Chaoxi Cui, Ying Liu +2
An electron beam may experience an anomalous spatial shift during an interface scattering process. Here, we investigate this phenomenon for reflection from mirror-symmetry-protecte…
Floquet control of topological phases and Hall effects in Z2 nodal line semimetals
Pu Liu, Chaoxi Cui, Lei Li +3
Dynamic control of topological properties in materials is central to modern condensed matter physics, and Floquet engineering, utilizing periodic light fields, provides a promising…
Anomalous shift in Andreev reflection from side incidence
Runze Li, Chaoxi Cui, Ying Liu +2
Andreev reflection at a normal-superconductor interface may be accompanied with an anomalous spatial shift. The studies so far are limited to the top incidence configuration. Here,…
