Construction of new description of atomic nuclei using superstring theory

The holographic principle which was discovered in superstring theory is a useful tool for analyzing strongly coupled gauge theories such as Quantum chromodynamics (QCD) which governs the dynamics of quarks. In particular, due to the strong coupling of the QCD, quarks form a bound state known as nucleons, and the nucleons form a bound state which is nothing but an atomic nucleus. Solving the dynamics of the quarks is directly resulting in a possible analysis of hadrons and nuclei by using the higher dimensional gravity theory. In this research, we constructed a gravity dual of a heavy atomic nucleus, and succeeded in calculating the radius of the atomic nucleus and also nucleon density profile. Furthermore, we calculated various hadronic properties and also made an application to condensed matter physics.
