Week 46, November 10-14


Week 46, November 10-14, 2025

  1. Linked and unlinked diagrams, Linked diagram theorem and diagram rules, summary
  2. Start coupled cluster theory
  3. Second midterm at https://github.com/ManyBodyPhysics/FYS4480/blob/master/doc/Exercises/2025/SecondMidterm2025.pdf

Friday's lecture

  1. Presentation and discussion of second midterm
  2. Coupled Cluster theory
  3. Relevant reading for the lectures: Shavitt abd Bartlett chapters 6 and 7 on linked and unlinked diagrams. For coupled cluster theory chapter 9 is the most relevant one. The lectures follow to a large extent the material covered in these chapters.
