Condensed Matter Physics

Hi, I’m Jiale Xuan

Welcome to my personal website! I am interested in quantum many-body problems in condensed matter physics, such as flat-band systems and the interplay between interactions and quantum geometry. Understanding strongly correlated physics has long been a central goal of mine. I enjoy combining analytical methods with numerical calculations to understand the physics of these systems.

This website is a record of what I am learning and exploring. It also serves as my personal ‘cloud archive’: a place to keep these materials within easy reach, so I can pull them up and share them whenever a discussion calls for them. If you happen to come across this collection and find something useful, I would be all the happier for it.
