Dr. Watanabe is a post-doctoral researcher at the Weizmann Institute of Science, working in the field of quantum field theory, string theory and mathematical physics. He received his Ph.D. from Kavli IPMU, the University of Tokyo, under the supervision of Prof. Simeon Hellerman. His doctoral research focused on a new method of quantum field theory called the large charge expansion, and on quantum information theory and its application to quantum gravity. He subsequently worked for six months as a postdoctoral researcher under Susanne Reffert at the Albert Einstein Center for Fundamental Physics, University of Bern.

 

Dr. Watanabe’s current research interests lie in general quantum field theory and holographic ideas in the theory of quantum gravity. He is seeking to apply the method of large charge expansion to systems with topological degrees of freedom, in order to understand various dualities that lie behind them. He is also working on the obstruction of lattice realizations of continuum field theories in odd dimensions, at the interface of condensed matter and high-energy physics. At the same time, he is continuing his work on the application of theoretical ideas on quantum information to quantum gravity, in which context he is examining various causality constraints of holographic theories.
