After completed course, the PhD student should be able to:

• apply Dirac's bracket notation.
• use Hermitian and non-Hermitian operators.
• know the path integral formalism of quantum theory.
• have knowledge about the matrix formulation of quantum mechanics and use density matrices.
• compute angular momentum and spin as well as have a good command of addition of angular momenta.
• use the variational principle and the WKB approximation.
• know the Aharonov-Bohm effect.
• have general knowledge about scattering theory as well as compute basic quantities in scattering theory.

If the course is discontinued, students may request to be examined during the following two academic years.

• TEN1 - Written exam, 5.0 credits, grading scale: P, F
• TEN2 - Oral exam, 2.5 credits, grading scale: P, F

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.

A written and oral exam.

Jens Bardarson

• 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.
