| Outline of Final Research Achievements |
In this project we studied spin-electicity conversion on the surface of topological insulators, magnetotransport, magnetization dynamics, and spintronics application in magnetic Weyl semimetals. In the first half we worked on novel electromagnetic responses on the surface of topological insulators, and in the second half we worked on a derivation of an effective field theory of magnetic Weyl semimetal with magnetic textures, magnetization dynamics, anisotropic magnetotransport. We also studied novel topological thermal responses in topological superconductors focusing on Majorana fermions and their quantized thermal Hall effect at the surface.
