Into Rabbit Hole of Quantum Again
It has been half a year since my last post, and I forgot to post a plan for the year 2022. So first some recent updates about my physics study.…
Geometric aspect of classical mechanics
There are many approaches to classical mechanics. The first introduction in high school is intuitive and fit into our everyday experience: motion of a single particle is some trajectory in…
Quantum Theory of Solids by Subir Sachdev
I started Prof. Sachdev's Havard course Physics 295b: Quantum Theory of Solids in the end of October 2021, and finished the first 30 lecture videos in the beginning of February…
A fascinating series of lectures on Psychology, Existentialism, personality and the transformation of personality by Dr. Jordan Peterson
One of my plans for non-physics life for year 2021 is to study more about Existentialism. See the last paragraph of my new-year-plan post this year. For those who never…
From the Ising model to the $\phi^4$ field theory
It has been a long time since my last post. I never expected that the graduate season, even for a Master's course, would be so busy. I prepared for 1)…
Many-body physics and black hole physics
During the May, I have been preparing for an application of a research funding called Research Fellowship for Young Scientists (特別研究員), provided by Japan Society for the Promotion of Science…
Non-physics goals for 2021
I want to set a few non-physics goals for this year. Dipping my toe into other fields always enriches my life. During my undergrad study in Tongji University, it was…
Harvard Justice
I finally finished watching all the video lectures of the famous Harvard lecture about political philosophy called Justice on 23 March. In 24 lectures, each about 25 minutes, Professor Michael…
Quick pass on several Conformal Field Theory notes
My master research topic is about developing new numerical methods (see our paper) to analyze critical phenomena; the conformal field theory (CFT) is one of the most important languages to…
Value of strategy: a financial theory example
Having studied mathematics and physics for a long time, I develop a view that we can get an edge in any game related to gambling by adopting a probabilistic understanding…
