RESEARCH

My research interests have been topological excitations and other phenomena related to topology. I started my research career with study about topological solitons such as instantons or vortices, which have non-trivial topology in the configuration space. Also I developed a new method of the quantum tunneling, and studied the Seiberg-Witten theory and supersymmetry.　Recently, my research has been focused on topological phases and topological orders, which cannot be explained by the scenario of the spontaneous symmetry breaking.

In this project, I will study theoretical aspects of topological condensations. In particular, I am interested in phenomena specific to topological superconductors, and non-Abelian topological anyons, which, for example, can be realized by the spin-orbit interaction and the Zeeman magnetic field.
