About me

Hi there, my name is Xinyu Xiang. I'm currently an undergraduate student in the Department of Physics at Tsinghua University. I am primarily interested in the non-perturbative structure of quantum field theory and its mathematical foundations, including quantization, deformation, duality, and holography.

Beyond physics, I enjoy programming—especially writing plugins for Neovim—to enhance productivity. I maintain an open-source personal configuration and several plugins on GitHub.

I am also a fan of tennis, playing weekly matches with friends at the Zijing Tennis Court (紫荆网球场).

About this blog

This blog focuses on:

  • Physics and math notes, with emphasis on non-perturbative QFT and related mathematical structures/tools.
  • Programming and tooling, including Neovim, web development, typst, productivity tips, etc.
  • Some personal stuffs.

It is built with tylant, a Typst-based static site generator.
