TOKAI UNIVERSITY Researchers Guide 2020

My research area is string theory, which is a candidate for a fundamental framework which may unify quantum mechanics and the general theory of relativity. I am in particular interested in using string theory to uncover various aspects of physics and mathematics, which are difficult to be addressed in a conventional manner. Recently I have worked on superconformal field theories in diverse dimensions using branes in string theory. The brane techniques in fact provide a geometric understanding of various features of the superconformal eld theories.ResearchAreasMathematical and physical sciencesKeywords■String theory■Quantum eld theory■Particle physicsRelatedresearchSDGExploring physics and mathematics via string theoryJunior Associate ProfessorHirotaka HayashiUndergraduate School of ScienceDepartment of PhysicsCondensed matter physics is an academic led which predicts, proposes, and elucidates a variety of characteristics of materials, based on the microscopic laws of physics. Since this research eld was historically developed on the assumption that the materials are in thermal equilibrium, there remain many questions if the materials are in non-equilibrium. In our research, we are interested in the development of fundamental theories for semiconductor optical physics (e.g. semiconductor lasers) and for non-equilibrium statistical physics.ResearchAreasMathematical and physical sciencesKeywords■Non-equilibrium condensed matter physics■Semiconductor optical physics■Non-equilibrium statistical physicsRelatedresearchSDGCondensed matter physics in non-equilibriumJunior Associate ProfessorMakoto YamaguchiUndergraduate School of ScienceDepartment of PhysicsWater is a ubiquitous, unique, and special substance. Water molecules interacting with other molecules form various structures and exert advanced functions. However, those molecular mechanisms have not been understood yet because of serious difficulties in observation and analysis for the hierarchical and broadband dynamics. We have developed a unique broadband dielectric spectroscopy (BDS: 1 μHz - 65 GHz) system with the fractal analysis of water structures. Our universal technique makes it possible to understand those molecular mechanisms and offer various evaluation systems for advanced functions and health of aqueous systems from concrete to human bodies treated in extensively wide research elds.ResearchAreasMathematical and physical sciencesKeywords■Water structures■Fractal analysis■Physics in life phenomena■Food science■Electromagnetic aquametryRelatedresearchSDGDevelopment and application of new fractal analysis of water structures in molecular complex and biological systems using broadband dielectric spectroscopy and complementary techniquesProfessor (-2019)Shin YagiharaUndergraduate School of ScienceDepartment of Physics63
