| Outline of Final Research Achievements |
In the study of two-dimensional conformal field theories, which are a class of quantum systems that are essential in understanding string theory, we invented a novel quantization scheme that leads the continuous spectrum of the system as well as a set of conserved charges that are indexed by a continuous variable. The introduction of the new quantization scheme enables the natural understanding of the phenomenon known in the study of quantum critical systems as Sine Square Deformation. It further clarifies the physics behind the phenomenon.
