Theoretical physics (particle physics, field theory, string theory)

Superstring theory is the most promising candidate for the quantum unification of space, time and matter. I have been working on its nonperturbative formulation, i.e. matrix models, to investigate the origin of our four-dimensional world. I am also interested in field theoretic description of condensed matter physics, the history of early universe and black holes.

Main fields: Quantum Field Theory and Foundation of Quantum Mechanics. I have been studying the mathematical foundation of quantum mechanics, especially on possible quantization schemes for systems which have nontrivial topological structures (e.g., singularities or defects). Applied in gauge field theories, these structures lead to intriguing physical phenomena such as solitons and anomalous symmetry breaking which are crucial both in the Standard Model of particle physics and string theory. I am also interested in the non local aspects of quantum mechanics and their application in various fields, for instance, in quantum game theory where entangled states (strategies) may resolve dilemmas in conventional game theory.

Lattice gauge theory has been useful in studying various nonperturbative phenomena in QCD such as quark confinement. One of the lines of research I have been pursuing for years is the application of analogous nonperturbative approaches to dynamical issues in quantum gravity, string theory and non-commutative geometry. For instance, I have been studying matrix models to investigate the possibility that four-dimensional space-time and the standard model gauge group appear dynamically from ten-dimensional superstring theory. I am also interested in applying lattice gauge theory to the study of chiral fermions and finite temperature systems.

Bear in mind a big dream, and try to proceed towards it step by step by doing down-to-earth research. Through collaborations and daily discussions, I hope to share with you the joy of new discovery and the joy of gaining deeper understanding in Nature.

Background free quantum gravity and cosmology. There are two formulations to describe background-metric independent quantum space-time in four dimensions. One is a numerical method for quantizing gravity carried on the simplicial space-time manifold. The other is a renormalizable theory of gravity on the basis of a conformal gravity. I have mainly been studying the latter, and my recent interest is to understand early universe by the renormalizable quantum gravity.
