    Dualities in String/M-theory and Quantum Gravity

    Group Introduction

    String/M-theory is a strong candidate for quantum gravity and provides a theoretical framework for unifying various interactions in nature. In this research group, we study the structure of classical and quantum gravity via various fascinating ideas in string/M-theory, especially dualities, and exploit them to various interesting problems. It encompasses scattering amplitudes, black hole physics, gauge/gravity duality, double copy, and the mathematical structure of stringy geometry.

      String theory and M-theory, the nonperturbative version of string theory, are supposed to be one of the strong candidates of quantum gravity and provides a theoretical framework of unification of various interactions in nature. In this research group, we focus on the basic structures and properties of classical and quantum gravity via various fascinating ideas in string/M-theory, especially dualities. It encompasses scattering amplitude, gauge/gravity duality, double copy, higher spin theory and mathematical structure of stringy geometry.
