Higher-dimensional Wannier interpolation for the modern theory of the Dzyaloshinskii-Moriya interaction: Application to Co-based trilayers
Jan-Philipp Hanke, Frank Freimuth, Stefan Blügel +1
We present an advanced first-principles formalism to evaluate the Dzyaloshinskii-Moriya interaction (DMI) in its modern theory as well as Berry curvatures in complex spaces based o…
Chiral and Topological Orbital Magnetism of Spin Textures
Fabian R. Lux, Frank Freimuth, Stefan Blügel +1
Using a semiclassical Green's function formalism, we discover the emergence of chiral and topological orbital magnetism in two-dimensional chiral spin textures by explicitly findin…
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…
