SI2600 Condensed Matter Theory 7.5 credits

This course in condensed matter theory treats central principles and computation methods, and covers some of the most recent research problems in the area. The approach is towards reaching important results by direct and intuitive methods, and avoiding unnecessary mathematical complexity. The course focuses on the quantum mechanical treatment of the solid state and covers many problems of current interest such as superconductivity, mesoscopic physics, and the quantum Hall effect. The course discusses methods for computation and making interesting predictions for some of the many complex phenomena that occur in solids and quantum liquids. The course is aimed primarily at advanced undergraduate students and PhD students in physics and related areas. The course is also aiming at scientists working with applications on electrical properties of materials.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade

Homework problems (INL1; 4,5 university credits) and oral examination (TEN1; 3 university credits).

Opportunity to complete the requirements via supplementary examination

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
