|Intro.||We study diverse physics problems that can be understood by the field theory and string theory. Our recent research focuses on the Gauge/Gravity duality.
Strongly coupled phenomena, such as color confinement, chiral symmetry breaking, high Tc superconductor, and non-Fermi liquid are long and outstanding unsolved problems in physics. The Gauge/Gravity duality (AdS/CFT duality), developed from string theory, provides a novel tool for studying strongly coupled systems by mapping difficult strong coupling problems to tractable classical gravity problems in higher dimensions (holographic principle or holography). We study both the formal aspects of the Gauge/Gravity duality and its practical application to diverse systems.
