Electronic structure in a transition metal dipnictide TaAs2
Sabin Regmi, Cheng-Yi Huang, Mojammel A. Khan +11
The family of transition metal dipnictides (TMDs) has been of theoretical and experimental interest because this family hosts topological states and extremely large magnetoresistan…
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…
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-…
Observation of Fermi arcs and Weyl nodes in a non-centrosymmetric magnetic Weyl semimetal
Anup Pradhan Sakhya, Cheng-Yi Huang, Gyanendra Dhakal +15
Weyl semimetal (WSM), a novel state of quantum matter, hosts Weyl fermions as emergent quasiparticles resulting from the breaking of either inversion or time-reversal symmetry. Mag…
High Spin-Chern-Number Insulator in -Antimonene with a Hidden Topological Phase
Baokai Wang, Xiaoting Zhou, Yen-Chuan Lin +2
In investigating the topological electronic structures of monolayer -phase group V elements, we uncover a new topological phase, which is invisible in the symmetry-based topolog…
A Higher-Order Topological Insulator Phase in a Modulated Haldane Model
Baokai Wang, Xiaoting Zhou, Hsin Lin +1
We explore topological properties of a modulated Haldane model (MHM) in which the strength of the nearest-neighbor and next-nearest-neighbor terms is made unequal and the three-fol…
