RESEARCH
I have studied topological insulators theoretically. Specifically, I have investigated charge and spin transport in the junction of a topological insulator, edge states in the vicinity of Brillouin zone boundary, and stability and criticality for disorder and Rashba spin-orbit interaction.
In this project, I will study topological superconductors in addition to topological insulators, and these junction/competitive systems. I will reveal its transport properties and effects of disorder.
