Discovery of Ĉ rotation anomaly in topological crystalline insulator SrPb
Wenhui Fan, Simin Nie, Cuixiang Wang +12
Topological crystalline insulators (TCIs) are insulating electronic states with nontrivial topology protected by crystalline symmetries. Recently, theory has proposed new classes o…
Time-reversal symmetry breaking driven topological phase transition in EuB
Shun-Ye Gao, Sheng Xu, Hang Li +16
The interplay between time-reversal symmetry (TRS) and band topology plays a crucial role in topological states of quantum matter. In time-reversal-invariant (TRI) systems, the inv…
Quasiparticle Interference Evidence of the Topological Fermi Arc States in Chiral Fermionic Semimetal CoSi
Qian-Qian Yuan, Liqin Zhou, Zhi-Cheng Rao +13
Chiral fermions in solid state feature "Fermi arc" states, connecting the surface projections of the bulk chiral nodes. The surface Fermi arc is a signature of nontrivial bulk topo…
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…
Dirac surface states in intrinsic magnetic topological insulators EuSn2As2 and MnBi2nTe3n+1
Hang Li, Shun-Ye Gao, Shao-Feng Duan +24
In magnetic topological insulators (TIs), the interplay between magnetic order and nontrivial topology can induce fascinating topological quantum phenomena, such as the quantum ano…
New classes of chiral topological nodes with non-contractible surface Fermi arcs in CoSi
Z. -C. Rao, H. Li, T. -T. Zhang +18
In condensed matter systems, chiral topological nodes are robust band crossing points in momentum space that carry nonzero Chern numbers. The chirality is manifested by the presenc…
