Feature-energy duality of topological boundary states in multilayer quantum spin Hall insulator
Yueh-Ting Yao, Xiaoting Zhou, Yi-Chun Hung +3
Gapless topological boundary states characterize nontrivial topological phases arising from the bulk-boundary correspondence in symmetry-protected topological materials, such as th…
Feature Spectrum Topology
Baokai Wang, Yi-Chun Hung, Xiaoting Zhou +2
Topology is a fundamental aspect of quantum physics, and it has led to key breakthroughs and results in various fields of quantum materials. In condensed matters, this has culminat…
Generation of isolated flat bands with tunable numbers through Moiré engineering
Xiaoting Zhou, Yi-Chun Hung, Baokai Wang +1
Unlike the spin-1/2 fermions, the Lieb and Dice lattices both host triply-degenerate low-energy excitations. Here, we discuss Moiré structures involving twisted bilayers of these l…
Topological chiral kagome lattice
Jing-Yang You, Xiaoting Zhou, Tao Hou +8
Chirality, a fundamental structural property of crystals, can induce many unique topological quantum phenomena. In kagome lattice, unconventional transports have been reported unde…
Time-Reversal Soliton Pairs In Even Spin-Chern-Number Higher-Order Topological Insulators
Yi-Chun Hung, Baokai Wang, Chen-Hsuan Hsu +2
Solitons formed through the one-dimensional mass-kink mechanism on the edges of two-dimensional systems with non-trivial topology play an important role in the emergence of higher-…
Transverse circular photogalvanic effect associated with Lorentz-violating Weyl fermions
Mohammad Yahyavi, Yuanjun Jin, Yilin Zhao +9
Nonlinear optical responses of quantum materials have recently undergone dramatic developments to unveil nontrivial geometry and topology. A remarkable example is the quantized lon…
