Outline of Final Research Achievements

We have studied superstring theory, -- a promising candidate of the theory of quantum gravity, which unifies quantum mechanics and general relativity. In particular, we have developed numerical techniques for quantitative calculations utilizing supercomputers. By using them we have tested the gauge/gravity duality conjecture with high precision, and confirmed that gauge theory correctly describes quantum nature of gravity. We expect that our result can lead to a new research field: numerical simulation of quantum gravity.
