Curvature-Controlled Topological Magnon Phases in a Folded Kagome Lattice
Seif Alwan, Jonas Fransson
We show that geometric curvature, encoded in the folding angle between two corner-sharing triangles on a kagome lattice, provides a continuous tuning knob for topological magnon ph…
Emergent Topology in Kagome Ferromagnets
Seif Alwan, Jonas Fransson
We investigate the emergence of a topological magnon phase in a two-dimensional kagome ferromagnet with Dzyaloshinskii-Moriya interaction (DMI) and scalar spin chirality. By incorp…
Dynamic Breaking of Mirror Symmetry in Spin-Dependent Electron Transport through Chiral Media Causes Enantiomeric Excesses
Yossi Paltiel, Daniel Goldberg, Nir Yuran +9
Two fundamental questions have puzzled scientists for more than 150 years. How did life become homochiral and why was this specific handedness selected. Recently, it has been shown…
An argument why the Spinterface model cannot explain the chirality induced spin selectivity effect
J. Fransson
In the context of chirality induced spin selectivity effect, it has been argued that a chiral molecule when adsorbed on a metal facilitates the formation of a local spin moment at…
Should it really be that hard to model the chirality induced spin selectivity effect?
J. Fransson
The chirality induced spin selectivity effect remains a challenge to capture with theoretical modeling. While at least a decade was spent on independent electron models, which comp…
Breaking of Time-Reversal Symmetry and Onsager Reciprocity in Chiral Molecule Interfacd with an Environment
J. Fransson
Molecular closed shell structures are known to form spin-singlet configurations, resulting from the spin-exchange associated with electron-electron interactions. While the vanishin…
