Weyl Semimetals with symmetry
Yuting Qian, Jiacheng Gao, Zhida Song +4
In the time-reversal-breaking centrosymmetric systems, the appearance of Weyl points can be guaranteed by an odd number of all the even/odd parity occupied bands at eight inversion…
Chiral fermion reversal in chiral crystals
Hang Li, Sheng Xu, Zhi-Cheng Rao +13
In materials chiral fermions such as Weyl fermions are characterized by nonzero chiral charges, which are singular points of Berry curvature in momentum space. Recently, new types…
BaHgSn: A Dirac semimetal with surface hourglass fermions
Tan Zhang, Zhihai Cui, Zhijun Wang +2
We proposed that BaHgSn is a Dirac semimetal (DSM) which can host hourglass-like surface states (HSSs) as protected by nonsymmorphic glide symmetry. Compared to KHgSb, an isostruct…
Layer Construction of Topological Crystalline Insulator LaSbTe
Yuting Qian, Zhiyun Tan, Tan Zhang +5
Topological crystalline insulator (TCI) is one of the symmetry-protected topological states. Any TCI can be deformed into a simple product state of several decoupled two-dimensiona…
Phononic Helical Nodal Lines with Protection in MoB
T. T. Zhang, H. Miao, Q. Wang +9
While condensed matter systems host both Fermionic and Bosonic quasi-particles, reliably predicting and empirically verifying topological states is only mature for Fermionic electr…
A diagnosis scheme for topological degeneracies at high-symmetry momenta
Tiantian Zhang, Ling Lu, Shuichi Murakami +3
Theories of symmetry-based indicators and topological quantum chemistry, while powerful in diagnosing gapped topological materials, cannot be directly applied to diagnosing band de…
