Master Thesis
I mainly concentrated on the numerical study of the quantum field theory using the stochastic quantization method during my master’s program. My collaborators and I developed a new method to calculate the contribution of the nonlinear (quartic) term in the scaler field in one- and three-dimensional discretized space-time, using the complex Langevin equation. This method, now called RPSA (Restricted Phase-Space Approximation), enabled us to estimate the nonlinear effects in non-equilibrium cases.

I focused on the experiments in the realm of quantum information, and performed an experiment to determine the behavior of interferometer made of micro-size thin membrane of sapphire amorphous.

I have some basis in numerical simulations and quantum physics, especially in the quantum field theory. However, I am completely new to the world of attosecond dynamics of molecules under the influences of intense laser fields. Thus, to become a member of Ishikawa Lab. was a challenging decision for me. Now I am really satisfied with the members from wide varieties of backgrounds, such as chemistry, experimental physics, as well as theoretical physics. I am also motivated by the ambitious research topics in this laboratory.
