I took ph.D on the quantum Hall effect at Univ. Tokyo.
I studied numerical scaling methods while working at PTB Germany as a post doctral fellow.
I developed scaling of the level statistics at Osaka and Toho universities.
After moving to Sophia University, I have been studing the localization and conductance scaling properties. The main focus of recent research is on the topological insulators and superconductors.Tomi Ohtsuki, Doctor of Science (University of Tokyo, 1989), is Professor of physics at Sophia University, Tokyo, where he conducts theoretical and computational researches in condensed matter physics. His recent research focuses on quantum transport phenomena such as the Anderson transition, conductance fluctuations, Hall and spin Hall effects in nanoscale systems. He has taught physics for more than 15 years in several universities and graduate schools. His research has been published by Physical Review Letters, Physical Review B, Physics Reports, and others.
The main classes he has are mechanics, electromagnetics, linear algebra, statistical physics as well as solid state physics.(Subject of research)
Numerical Study of Anderson transitions
spin related quantum transport phenomena
