img Research Field
Infinity number of particles exibit many different phases that have different properties. To solve the problems how these properties appear in the physical systems of the infinity number of particles are the purpose of my research. Identical particles can not be distingusihed each others in microscopic world. Many identical particles are expresed by one field and by solving the field theory we are able to know the physical properies of the systems. Fundamental problems of quantum field theory is the topic of my research.
