I’m currently working on the following activities.

Physics study (Updated on 3 June 2023)

I’m now studying Polyakov’s course, Modern Classical Dynamics, by watching the video lectures recorded at Princeton in 2013. You can find the course syllabus and summary in this old website of Princeton (may not work properly) or this pdf file I made for my personal convenience.

My plan is to watch two videos per week. Now, I’ve finished watching the first ten lectures and love them! Here are my personal notes (first eight lectures done, more to come…) for this course.

Physics Research

[Newest] The work with Jim Freericks is published in Atoms on 26 Jan. The paper uses an operator method to solve the textbook Hydrogen (like what we do for the textbook Harmonic oscillator). Also see Jim’s video lecture about this here.

[old] I’ve finished my first research project at UTokyo under Prof. Kawashima’s supervision. It is about numerical renormalization group in the context of tensor-network-based techniques. You can find the e-print of this paper in arXiv here. The paper was published in Physical Review Research on 16 April 2021.

I graduated from the Master’s course on September 2021.
My thesis is based on the above paper, with more introductory material on renormalization group.

We are now working on generalizing the method from 2D to 3D systems.

Non-physics interesting things

After finishing watching the 2017 psychology lecture video of the Toronto Professor Jordan Peterson, Personality and its Transformation, I start reading his 1999 book, Maps of Meaning: The Architecture of Belief. His understanding of the world as a superposition of order and chaos is exceptionlly interesting!

Random thoughts

I’m quite into a quote from Carl Jung recently. I heard it from Dr. Peterson’s lectures. Here is the quote,

Everybody acts out a myth, but very few people know what their myth is. And you should know what your myth is because it might be a tragedy and maybe you dont want it to be.
― Carl Jung

It reminds me of an old maxim know yourself! It also rings a bell with a guy who has put too much endeavor and focus on the factual aspect of the world (including what inside and outside myself), but has ignored the internal deep meaning of it (what makes it worthwhile to do?).

This quote conveys an idea like this: you should assign the meaning to your life yourself. Really design it like a machine or bridge, or tell a story about it like what you are doing when talking to a good friends and then act your story out!. You can choose to be the main character or any other peripheral characters in your story of life.

I plan to do something about knowing myself and how is my story like recently.
