Tensor Theory for Higher Dimensional Chern Insulators with Large Chern Numbers
Kai Wang, Jia-Xiao Dai, L. B. Shao +2
Recent advances in topological artificial systems open the door to realizing topological states in dimensions higher than the usual three-dimensional space. Here, we present a "ten…
Tensor monopoles and negative magnetoresistance effect in optical lattices
Hai-Tao Ding, Yan-Qing Zhu, Zhi Li +1
We propose that a kind of four-dimensional (4D) Hamiltonians, which host tensor monopoles related to quantum metric tensor in even dimensions, can be simulated by ultracold atoms i…
Boundary criticality of -invariant topology and second-order nodal-line semimetals
Kai Wang, Jia-Xiao Dai, L. B. Shao +2
For conventional topological phases, the boundary gapless modes are determined by bulk topological invariants. Based on developing an analytic method to solve higher-order boundary…
Four-Dimensional Topological Insulators with Nodal-Line Boundary States
L. B. Shao, Y. X. Zhao
Conventional topological insulators and superconductors have topologically protected nodal points on their boundaries, and the recent interests in nodal-line semimetals only concer…
Controlling Fusion of Majorana Fermions in one-dimensional systems by Zeeman Field
L. B. Shao, Z. D. Wang, R. Shen +3
We propose to realize Majorana fermions (MFs) on an edge of a two-dimensional topological insulator in the proximity with s-wave superconductors and in the presence of transverse e…
Stabilization of Quantum Spin Hall Effect by Designed Removal of Time-Reversal Symmetry of Edge States
Huichao Li, L. Sheng, R. Shen +4
The quantum spin Hall (QSH) effect is known to be unstable to perturbations violating time-reversal symmetry. We show that creating a narrow ferromagnetic (FM) region near the edge…
