Final exam

Dear all, since our discussions last Friday (November 29) were in Norwegian only, no recording was made. However, here follows a brief summary of a possible path for the oral exam.

1) You should make a presentation which lasts approximately 25-30 minutes. Only slides, no blackboard/whiteboard or plain paper and pencil presentations.

2) We will use the last 15-20 mins on questions about your presentation and eventually other topics we have covered this semester. The questions will mainly focus on what you presented, but can also include general background questions about many-body theories in order to assess your understanding.

What should I include in the  presentation?

You should try to cover the main many-body methods we have covered this semester, their mathematical background, pros and cons and possible links with each other. The methods we have discussed are

a) Full configuration interaction theory

b) Hartree-Fock theory and mean field theory (but we don't include DFT)

c) Many-body perturbation theory, both Brillouin-Wigner and Rayleigh-Schroedinger perturbation theory

d) Coupled-Cluster theory at the level of doubles and singles and doubles excitations

Topics like second quantization, Wick's theorem, particle-hole formalism can also me mentioned and discussed, but can in general be seen as part of the general technical background needed in order to discuss the above methods. You don't need to dedicate many slides on these topics.

In order to discuss the above methods, the results from the two midterms can be used to illustrate the various methods. For coupled cluster theory, you can for example compare the results from the second midterm using for example the code discussed during week 47 and week 48, see  for example the jupyter-notebook from week 47 at https://github.com/ManyBodyPhysics/FYS4480/tree/master/doc/pub/week47/ipynb

Chapters 1-7 and 9-10 of Bartlett and Shavitt and chapters 1-6 of Szabo and Ostlund cover most of the topics we have discussed this semester.

We hope this can be of some use. Don't hesitate to ask questions. You should also have received information from the study administration about the final exam schedule. Let us know if this is not the case. The exam can be in person or via zoom.

The final dates are Monday December 16 9am-5pm and Tuesday December 17 9am-12pm.

best wishes to you all,

Morten and Ruben
