Tatsuki Tojo

Tatsuki Tojo is an Assistant Professor in the Department of Electrical Engineering and Bioscience at Waseda University. He holds a Doctor of Science (2022) from the same institution.

• Education: Ph.D. (2022), M.Sc. (2019), B.Sc. (2017) in Advanced Science and Engineering

Research Focus: His work centers on quantum materials science, particularly the interplay between spin-orbit interactions and topological phases in semiconductor quantum wells. Key themes include:

• Non-Abelian Berry phase dynamics
• Spin textures and Larmor precession
• Quantum logic gate representation of spin behavior
• π-quantization of Berry phases

Publications: He has authored 11 refereed papers with 24 citations (h-index: 3), exploring phenomena like Rashba/Dresselhaus spin-orbit coupling in SiGe, Si, and diamond-based systems. Notable contributions include logic gate analysis for topological phases and quantized Berry phase models.

Academic Engagement: Active in major international conferences including APS March Meeting, MRS Fall Meeting, and International Conference on Low Temperature Physics (2016–2025). Served as lead/corresponding author in multiple studies.

Laboratory Involvement: Participates in advanced research projects analyzing geometric phases and quantum confinement effects, with recent work on Bloch sphere representations of spin precession.
