高等固態物理（二）- Lec11 微擾理論：費曼圖與費曼規則(一) Perturbation theory: Feynman Diagram and Feynman Rules I

Whole-channel inclusion: NYCU OCW (title sample: This is an official university OpenCourseWare channel with full recorded lectures across math, engineering, humanities, and sciences, almost entirely genuine classroom teaching content.; 0 of 3 sampled transcripts read as real teaching); this title passed a strict title check.
