A Hamiltonian Approach for Obtaining Irreducible Projective Representations and the Perturbation for Anti-unitary Symmetry Groups
Zhen-Yuan Yang, Jian Yang, Chen Fang +1
As is known, the irreducible projective representations (Reps) of anti-unitary groups contain three different situations, namely, the real, the complex and quaternion types with to…
Symmetry-protected Nodal Points and Nodal Lines in Magnetic Materials
Jian Yang, Chen Fang, Zheng-Xin Liu
Nodal-point and Nodal-line structures in the dispersion of electron energy bands are characterized by their high degeneracy in certain corners or lines in the Brillouin zone (BZ).…
Unlocking of time reversal, space-time inversion and rotation invariants in magnetic materials
Jian Yang, Zheng-Xin Liu, Chen Fang
Time reversal () and space inversion are symmetries of our universe in the low-energy limit. Fundamental theorems relate their corresponding quantum numbers to the spin for elem…
Real-space recipes for general topological crystalline states
Zhida Song, Chen Fang, Yang Qi
Topological crystalline states are short-range entangled states jointly protected by onsite and crystalline symmetries. While the non-interacting limit of these states, e.g., the t…
