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…
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…
Mixed Weyl semimetals and dissipationless magnetization control in insulators by spin-orbit torques
Jan-Philipp Hanke, Frank Freimuth, Chengwang Niu +2
Reliable and energy efficient magnetization switching by electrically-induced spin-orbit torques is of crucial technological relevance for spintronic devices implementing memory an…
