Dear all, welcome back to FYS4480/9480. We hope this week has started the best possible way for you all.

This week we will continue our discussion of many-body perturbation theory and emphasize diagram rules and how to calculate higher contributions. In addition we will also discuss the so-called diagram theorem, which is a very important theorem for several many-body methods, such many-body perturbation theory, coupled cluster theory and Green's function theory. The plan this week is

Thursday:

a. Time-independent perturbation theory: examples of contributions in perturbation theory and diagrammatic representations

b. Diagram rules and their derivations

Friday:

a. Diagram examples

b. Linked diagram theorem

Note: Friday's lecture is a recording only, since I will be attending an all-day workshop, https://www.jus.uio.no/ifp/english/about/organization/nrccl/events/2025/xxxx-nordic-con...
