ABOUT US
TThe most fundamental objects in nature, known as "elementary particles," are described by a framework called "quantum field theory." Quantum theory explains microscopic phenomena, where the positions and velocities of particles are generally uncertain. In quantum field theory, even the existence of particles is uncertain—they can emerge from the vacuum and vanish just as easily. In our lab, we explore methods of analyzing quantum field theory and apply them to real-world phenomena to gain a deeper understanding of nature. Specifically, we aim to understand "quark confinement" and "mass gap generation," which lead to the formation of protons and neutrons, using both mathematical and computational approaches.
MESSAGE
All phenomena follow certain natural laws. Everything is made up of atoms and subatomic entities called elementary particles, whose behavior is governed by the law known as quantum theory. On the other hand, the behavior of stars and planets in space is dictated by the law of general relativity [Fig.1, 2]. Physicists believe these two laws are actually different aspects of a single, unified law, referred to as the "Theory of Everything." This theory could potentially describe all phenomena in nature. One goal of physics is to discover the universal law or equation underlying these phenomena. Another goal is to understand how this complex world arises from such a universal law. To pursue these aims, we study elementary particles [Fig.3] and quantum field theory.
