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…
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…
Magnetic topological insulator MnBi6Te10 with zero-field ferromagnetic state and gapped Dirac surface states
Shangjie Tian, Shunye Gao, Simin Nie +14
Magnetic topological insulators (TIs) with nontrivial topological electronic structure and broken time-reversal symmetry exhibit various exotic topological quantum phenomena. The r…
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…
