Education
- Bechelor of Science (Physics, first class honours), Mahidol University, 2016-2020
- Thesis title : High-precision Numerical Scheme for Quantum Trajectories
- Details: Thesis length 11,520 words, undertaken over two semesters full-time of the fourth year. In this thesis, I combined research results produced during my research visit at Centre for Quantum Dynamics, Griffith University, and during the fourth year of my honour program. In broad terms, I proposed a new approach for quantum-trajectory estimations, which is more precise and accurate than previously proposed methods. Moreover, I also made a comparison among all approaches both analytically and numerically, in order to show that my new approach is the most accurate one.
