Quantum field theory is a field of study that combines quantum mechanics, which describes microscopic phenomena, and special relativity, which describes high-energy phenomena. Historically, it has developed as a mathematical framework for describing the physics of elementary particles, as exemplified by the Standard Model. In recent years, it has attracted attention to other fields of physics, such as condensed matter physics, and its relevance to other fields, such as quantum information theory.
On the other hand, quantum field theory can only be investigated to an approximate extent; for example, when considering the quarks that make up atomic nuclei, it is not possible to calculate them analytically, and numerical calculations are used. Therefore, I would like to investigate quantum field theory mathematically in more detail and clarify its analytical properties. To achieve this, I am also interested in its connection with quantum information theory. Through my research, I aim to advance our understanding of quantum field theory and contribute to the development of physics.
