What is a proper definition of spin current? -- Lessons from the Kane-Mele Model
Tomohiro Tamaya, Takeo Kato, Takahiro Misawa
Spin current, a key concept in spintronics that carries spin angular momentum, has a non-unique definition due to the non-conservation of spins in solids. While two primary definit…

Diabatic Mechanisms of Higher-Order Harmonic Generation in Solid-State Materials under High-Intensity Electric Fields
T. Tamaya, A. Ishikawa, T. Ogawa +1
We theoretically investigate mechanisms of higher-order harmonic generation in solid-state materials under a high-intensity ac electric field. A new theoretical framework presented…

Higher-Order Harmonic Generation caused by Elliptically Polarized Electric Fields in Solid-State Materials
T. Tamaya, A. Ishikawa, T. Ogawa +1
We theoretically investigated the dependence of higher-order harmonic generation (HHG) in solid-state materials on the ellipticity of the electric field. We found that in the multi…
