Information

Ziele, Inhalte und Methode der Lehrveranstaltung

The basics of the perturbation expansion of Green and correlation functions to Feynman diagrams is overlaid with practical exercises. The target of exercises, evolving from trivial exactly solvable models to contemporary edge of precise many-body computational methods, is to develop practical skills in Diagrammatic Monte Carlo method and reach the level of competency sufficient for exact solving of exciton, polaron, and spin-boson models. Final introduction to the novel Bold Diagrammatic Monte Carlo method presents detailed recipes not yet covered by existing tutorial literature.

Art der Leistungskontrolle und erlaubte Hilfsmittel

Oral exam where student gets (i) simple and (ii) complicated theoretical question, (iii) one exercise made during the course, (iv) and one exercise similar to those made in course. Student gets up to one hour for preparation and can use any personal lecture notes.

Mindestanforderungen und Beurteilungsmaßstab

At the exam, (i)+(iii) or (iv) is enough to obtain a positive grade.

Prüfungsstoff

Exam theoretical topics include all topics covered in the lecture and exercises. In the exam, exercises are the same or similar to those discussed in the course. Derivations of Metropolis ratios and physical properties estimators.
