Outline of Chair

Research Fields

Quantum Physics of Condensed Matter - Research

Matter offers a place for the expression of a wide variety of quantum phenomena. The field of Quantum Physics of Condensed Matter is researched for the purpose of microscopic clarification of the electrical, magnetic, optical and mechanical properties of matter using quantum mechanics, statistical mechanics, electromagnetics and other disciplines.
Particularly in the case of novel properties of matter demonstrated under extreme environments, such as ultra-high pressure, ultra-cold temperature and intense magnetic fields, the mechanisms for expressing those properties and the universal physical laws hidden within are the subjects of experimental and theoretical research. Research and development is then carried out on materials science applications of those novel properties.

 

Elementary Particle and High Energy Physics - Research

In this field, theories and experiments are used to search for the smallest unit (elementary particle) used to form matter, and then research is carried out to clarify the forces and interaction involved in their movement.
On the theory side, research is carried out on the quantum field theory-based grand unified theory, supersymmetric theory, extra-dimensional theory, superstring theory and other theories, while research is also carried out on mathematical physics, which is the mathematical side of the study of physics.
On the experiment side, students are participating in the ATLAS group at the world’s largest LHC accelerator and in the development group at the next-generation ILC accelerator; research is being carried out on experimental verification of elementary particle theory and on the discovery of new particles using the accelerator; and new measurement apparatus are being researched and developed.

 

Cosmic Ray Physics - Research

In this field, experimental and theoretical research and education are carried out on high energy galactic cosmic ray modulation caused by solar activity.
High energy cosmic ray data and a wide variety of other data about solar, solar-wind plasma and interplanetary space magnetic fields, etc., collected through observation of radio waves from man-made satellites and terrestrial installations, are organically combined and analyzed, and research is then carried out on variations in solar movement and average structures of near-earth space environments and galactic magnetic fields near the heliosphere.
Students are also involved in joint research with the Solar-Terrestrial Environment Laboratory of Nagoya University and the Institute for Cosmic Ray Research of the University of Tokyo, and in international joint research for the purpose of furthering Shinshu University’s own measurements of global cosmic rays.
