Projective crystal symmetry and topological phases
Chen Zhang, Shengyuan A. Yang, Y. X. Zhao
Quantum states naturally represent symmetry groups, though often in a projective sense. Intriguingly, the projective nature of crystalline symmetries has remained underexplored unt…
Hilbert band complexes and their applications
Zeying Zhang, Y. X. Zhao, Yugui Yao +1
The study of band connectivity is a fundamental problem in condensed matter physics. Here, we develop a new method for analyzing band connectivity, which completely solves the outs…
Stability and noncentered PT symmetry of real topological phases
S. J. Yue, Qing Liu, Shengyuan A. Yang +1
Real topological phases protected by the spacetime inversion (P T) symmetry are a current research focus. The basis is that the P T symmetry endows a real structure in momentum spa…
Quantum Metric Nonlinear Spin-Orbit Torque Enhanced by Topological Bands
Xukun Feng, Weikang Wu, Hui Wang +5
Effects manifesting quantum geometry have been a focus of physics research. Here, we reveal that quantum metric plays a crucial role in nonlinear electric spin response, leading to…
Projective symmetry determined topology in flux Su-Schrieffer-Heeger model
Gang Jiang, Z. Y. Chen, S. J. Yue +4
In the field of symmetry-protected topological phases, a common wisdom is that the symmetries fix the topological classifications, but they alone cannot determine whether a system…
Spinless Mirror Chern Insulator from Projective Symmetry Algebra
L. B. Shao, Z. Y. Chen, K. Wang +2
It was commonly believed that a mirror Chern insulator (MCI) must require spin-orbital coupling, since time-reversal symmetry for spinless systems contradicts with the mirror Chern…
