Strain induced magnetic phase transition and anomalous transport phenomena in RuO and MnF

Xiuxian Yang, Zhangqi Wu, Xiangju Wang +6

Collinear antiferromagnets with broken time-reversal symmetry have emerged as a fertile platform for spintronics. Using a general tight-binding model and first-principles calculati…

General Electronic Structure Calculation Method for Twisted Systems

Junxi Yu, Shifeng Qian, Cheng-Cheng Liu

In recent years, two-dimensional twisted systems have gained increasing attention. However, the calculation of electronic structures in twisted material has remained a challenge. T…

Stable Higher-Order Topological Dirac Semimetals with Monopole Charge in Alternating-twisted Multilayer Graphenes and beyond

Shifeng Qian, Yongpan Li, Cheng-Cheng Liu

We demonstrate that a class of stable monopole charge Dirac point (DP) phases can robustly exist in real materials, which surmounts the understanding:…

Layer Construction of Three-Dimensional Z2 Monopole Charge Nodal Line Semimetals and prediction of the abundant candidate materials

Yongpan Li, Shifeng Qian, Cheng-Cheng Liu

The interplay between symmetry and topology led to the concept of symmetry-protected topological states, including all non-interacting and weakly interacting topological quantum st…

-symmetric higher-order topological crystalline insulators in atomically thin transition-metal dichalcogenides

Shifeng Qian, Gui-bin Liu, Cheng-Cheng Liu +1

Based on first-principles calculations and symmetry analysis, we predict atomically thin ( layers) 2H group-VIB TMDs ( = Mo, W; = S, Se, Te) are large-gap higher…

Second Order Topological Insulator State in Hexagonal Lattices and its Abundant Material Candidates

Shifeng Qian, Cheng-Cheng Liu, Yugui Yao

We propose two mechanisms to realize the second order topological insulator (SOTI) state in spinless hexagonal lattices, viz., chemical modification and anti-Kekulé/Kekulé distorti…
