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…
Making topologically trivial non-Hermitian systems nontrivial via gauge fields
W. B. Rui, Y. X. Zhao, Z. D. Wang
Non-Hermiticity significantly enriches the concepts of symmetry and topology in physics. Particularly, non-Hermiticity gives rise to the ramified symmetries, where the non-Hermitia…
Projective Spacetime Symmetry of Spacetime Crystals
Zheng Zhang, Z. Y. Chen, Y. X. Zhao
Wigner's seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counter…
Chess-board Acoustic Crystals with Momentum-space Nonsymmorphic Symmetries
Yanqiu Wang, Chen Zhang, Z. Y. Chen +3
Spatial symmetries appearing in both real and momentum space are of fundamental significance to crystals. However, in the conventional framework, every space group in real space, e…
Classification of time-reversal-invariant crystals with gauge structures
Z. Y. Chen, Zheng Zhang, Shengyuan A. Yang +1
A peculiar feature of quantum states is that they may embody so-called projective representations of symmetries rather than ordinary representations. Projective representations of…
Periodic Clifford symmetry algebras on flux lattices
Yue-Xin Huang, Z. Y. Chen, Xiaolong Feng +2
Real Clifford algebras play a fundamental role in the eight real Altland-Zirnbauer symmetry classes and the classification tables of topological phases. Here, we present another el…
