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…
