Optical-vortex-pulse induced nonequilibrium spin textures in spin-orbit coupled electrons
Shunki Yamamoto, Masahiro Sato, Satoshi Fujimoto +1
Optical vortex beams are a type of topological light characterized by their inherent orbital angular momentum, leading to the propagation of a spiral-shaped wavefront. In this stud…

Spin Seebeck Effect as a Probe for Majorana Fermions in Kitaev Spin Liquids
Yasuyuki Kato, Joji Nasu, Masahiro Sato +3
Quantum entanglement in strongly correlated electron systems often leads to exotic elementary excitations. Quantum spin liquids (QSLs) provide a paradigmatic example, where the ele…

Microscopic theory of spin Seebeck effect in antiferromagnets
Keisuke Masuda, Masahiro Sato
We develop a microscopic theory for the spin Seebeck effect (SSE) in Néel and canted phases of antiferromagnetic insulators. We calculate the DC spin current tunneling from the ant…
