Plans for week 39, September 26-30

Hi everybody, we hope the week has started the best possible way.
Last week we discussed the so-called particle-hole formalism nd we used that to rewrite our basis of Slater determinants in terms of  particle-hole excitations. The material is covered by Shavitt and Bartlett chapters 3 and 4 and the lecture notes.
This week the plan is 
Topics to be covered

Thursday:

Repetition of particle-hole formalism

Diagrammatic representation

Introduction of full configuration interaction theory

Friday:

Full configuration interaction (FCI) theory

Lipkin model as an example of applications of FCI theory

Lecture Material: These slides, handwritten notes and for the diagrammatic representation, Shavitt and bartlett chapter 4.

Fifth exercise set at https://github.com/ManyBodyPhysics/FYS4480/blob/master/doc/Exercises/2022/ExercisesWeek39.pdf

Best wishes to you all,
Morten and ?yvind
