I have written some notes about mathematics and physics.

  1. Condensed Matter Field Theory (in progress) Condensed matter physics is hard to get started for mathematicians/high energy theorists, who prefer a formal construction to messy calculation. However, it is a rich world that have motivated a lot of great concepts and will keep providing novel insights. I am making a map so that even people not familiar with solid state physics (both theory and experiment) are able to enter this land, messy but flowing with milk and honey. It’s still very incomplete and I am working to supplement it as long as I have time.
  2. Derived Algebraic Geometry (in preparation)
