Enhanced Spin Hall Response From Aligned Kramers-Weyl Points in High Chern Number Semimetals

C. O. Ascencio, Wei Jiang, D. J. P. de Sousa +3

We propose a spin Hall effect (SHE) enhancement mechanism due to Kramers-Weyl point (KWP) alignment in chiral topological semimetals with high Chern numbers (CNs). Through model Ha…
