Quantum Field Theory for condensed matter

This is an advanced course where the machinery of quantum field theory is applied to condensed matter systems.

Information for admitted students Spring 2021

Congratulations! You have been admitted at Stockholm University and we hope that you will enjoy your studies with us.

In order to ensure that your studies begin as smoothly as possible we have compiled a short checklist for the beginning of the semester.

Pre-departure information

New in Sweden

In this course we start from second quantization and study quantum field theoretical formulation of many particle theory. The concept of effective action and effective theory, such as mean field theory, is discussed, as well as other important concepts such as linear response theory and Fermi liquid theory. We also study quantum field theory at finite temperature, spontaneous symmetry breaking and phase transitions. Finally, topological effects in many particle systems are introduced.

Teaching during the spring semester 2021

During the spring semester 2021, lectures and problem will be given remotely through Zoom. The course will be examined through written home assignments and remote written examination.

The course is using the learning platform Athena.

  • Course structure

    This is a Master's level course, given in half pace during daytime.

    Teaching format

    The teaching consists of lectures and problem solving sessions. There will also be active learning elements, such as small group discussions and/or student presentations.


    Written exam at the end of the course, hand-in exercises, active participation in seminars.
