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…
Two-dimensional topological nodal line semimetal in layered ( = Ca, Sr, and Ba; = As, Sb, and Bi)
Chengwang Niu, Patrick M. Buhl, Gustav Bihlmayer +4
In topological semimetals the Dirac points can form zero-dimensional and one-dimensional manifolds, as predicted for Dirac/Weyl semimetals and topological nodal line semimetals, re…
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…
