| Outline of Research at the Start |
Our world is a quantum world, as we already knew for a century. However, the mathematics to describe a quantum world is still far from well-established. We work towards this mathematics relying on one of the most fundamental concepts in physics, symmetry.
|
| Outline of Annual Research Achievements |
In the first half of the last fiscal year, I completed my Ph.D. dissertation entitled "A Topological Origin for Generalized Symmetry" on the non-invertible and higher-categorical nature of the conservation law of topological solitons in quantum field theories. This dissertation excellently concluded my entire research period under JSPS Doctoral Course Research Fellowships and made the University of Tokyo award me a Ph.D. in theoretical physics. Subsequently, I quit JSPS Doctoral Course Research Fellowships and moved to the United States to continue theoretical physics research as a postdoctoral scholar.
