Research Field

My main interest is to explore and understand the ultimate properties of matter at extreme conditions such as the matter just after the Big-Bang. High energy nuclear collisions can create such hot and dense matter which was existed just after the Big-Bang. This state of matter is called Quark-Gluon Plasma (QGP). QGP is a new form of matter; protons and neutrons are melted to quarks and gluons. In particular, I am interested in understanding a spacetime evolution of matter created in the nuclear collisions.

    Matter changes its sate from solid, liquid, to gas according to the temperature and density. Around thousands of temperature, plasma state appears, which consists of ions. For example, the Sun is a plasma. What will happen when temperature or density is even higher?
    According to the Big-Bang cosmology, our universe began 13.8 billion years ago from Big-Bang. The highest temperature was achieved in the early universe. On the other hand, there are compact stars such as black holes and neutron stars. It is expected that the core of neutron star is the highest density in the current universe. We can explore high temperature and density state of matter by experiment in the laboratory by using high energy heavy-ion collisions. In this lecture, I introduce what we know about such extreme state of matter from high-energy heavy-ion collision.
