Construction of new description of atomic nuclei using superstring theory

在超弦理论中发现的全息原理是分析强耦合规范理论（如控制夸克动力学的量子色动力学）的有用工具。特别是，由于QCD的强耦合，夸克形成一种被称为核子的束缚态，而核子形成一种除了原子核之外什么都不是的束缚态。解决夸克的动力学问题直接导致了利用高维引力理论分析强子和原子核的可能。在这项研究中，我们构建了一个重原子核的引力对偶，并成功地计算了原子核半径和核子密度分布图。此外，我们还计算了各种强子性质，并将其应用于凝聚态物理。

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.
