Simulation studies of interaction between waves and
particles in a plasma
Plasma, a many-body system of electrically charged particles, behaves in a various and complex manner. I was fascinated by the physics of plasma and started my research. Plasma physics is not only the basis of fusion research, but also essential for understanding various phenomena in space.
A wide variety of waves exist in plasma, and these waves interact with the particles of the plasma. This interaction between waves and particles is one of the important physical processes common to fusion plasma and space plasma. As a result of this interaction, the particles can be accelerated by gaining energy from the wave, or conversely, the wave can grow larger as energy is transferred from the particle to the wave. And these phenomena are intricately intertwined. I am studying this problem using computer simulations, with special attention to kinetic instabilities and nonlinear waves such as soliton and shock waves.
Prior to my appointment at NIFS, I worked at Nagoya University, where I was involved in research and the education of students. In addition to these activities, I also work in public relations at NIFS, where I introduce the research results of NIFS. The photo was taken at a press conference where I was the moderator.
