Hidden wallpaper fermion and third-order topological insulator
Ning Mao, Hao Wang, Ying Dai +2
Nonsymmorphic symmetry can induce exotic wallpaper fermions, e.g., hourglass fermion, fourfold-degenerate Dirac fermion, and Möbius fermion, as commonly believed only in nonsymmorp…
Mixed topological semimetals driven by orbital complexity in two-dimensional ferromagnets
Chengwang Niu, Jan-Philipp Hanke, Patrick M. Buhl +6
The concepts of Weyl fermions and topological semimetals emerging in three-dimensional momentum space are extensively explored owing to the vast variety of exotic properties that t…
Quantum spin Hall effect and topological phase transitions in honeycomb antiferromagnets
C. Niu, J. -P. Hanke, P. M. Buhl +4
While the quantum spin Hall (QSH) effect and antiferromagnetic order constitute two of the most promising phenomena for embedding basic spintronic concepts into future technologies…
Topological Nodal-line Semimetals in Two Dimensions with time-reversal symmetry breaking
Chengwang Niu, Patrick M. Buh, Hongbin Zhang +4
Topological nodal-line semimetals (TNLSs) exhibit exotic physical phenomena due to a one-dimensional (1D) band touching line, rather than discrete (Dirac or Weyl) points. While so…
Robust Dual Topological Character with Spin-Valley Polarization in a Monolayer of the Dirac Semimetal NaBi
Chengwang Niu, Patrick M. Buhl, Gustav Bihlmayer +4
Topological materials with both insulating and semimetal phases can be protected by crystalline (e.g. mirror) symmetry. The insulating phase, called topological crystalline insulat…
Topological Crystalline Insulator and Quantum Anomalous Hall States in IV-VI based Monolayers and their Quantum Wells
C. Niu, P. M. Buhl, G. Bihlmayer +3
Different from the two-dimensional (2D) topological insulator, the 2D topological crystalline insulator (TCI) phase disappears when the mirror symmetry is broken, e.g., upon placin…
