Ph.D. (mathematical science)Research Projects
- Nonlinear Physics: Reaction-Diffusion Equations and Other Applied Mathematics
- Statistical Mechanics: Associative Memory Models and Derived Models
- Condensed Matter Physics: Quantum Dot Systems and Other Nanoscale Physics
The appeal of research
- In nonlinear physics, unexpected phenomena can occur. I believe one of its attractions is exploring the mechanisms behind them.
- Statistical mechanics encompasses a wide range of fields, but recent developments in associative memory models have focused on their application to information science. It's interesting how seemingly unrelated fields can share the same underlying principles.
- Nanoscale physics, such as quantum dot systems, is an important topic both in fundamental science and engineering. A future prospect for this research is its application to electronic devices.
Achievements
- In nonlinear physics, I have primarily dealt with reaction-diffusion systems. In particular, I have studied the properties of solutions in three-variable systems and two-variable systems with global feedback.
- In statistical mechanics, I have studied the stationary solutions and dynamics of several associative memory models.
- In quantum dot systems, we have studied the Kondo effect and the Aharonov-Bohm effect in single-quantum dot and two-quantum dot systems.

Attractive Factors of My Research
I research three different areas in physics. Nonlinear physics shows unexpected phenomena, it is one of the attractive factors. Statistical physics covers very wide areas in physics, recent development in associative memory model is application to information science. Although the research areas are different, their mechanism may be closely related, it is often surprising. Quantum dot physics is interesting topics for basic science and technology, it is promising for future electric devices.
Achievements
- In the nonlinear physics, I have devoted mainly to reaction diffusion (RD) systems. For three components RD system or two components RD system under global feedback, the properties of their systems were studied.
- In the statistical physics, I have studied several types of associative memory models. Stationary state of order parameters and their dynamical properties were examined.
- In the quantum dot (QD) system, I have studied Kondo effect and Aharonov-Bohm effect in a single and double QD systems.
