FYS4480 – Quantum mechanics for many-particle systems

Course content

This course gives an introduction to the quantum mechanics of many-body systems and the computational methods relevant for many-body problems in such diverse areas as atomic, molecular, solid-state and nuclear physics, chemistry and materials science. The topics covered are Feynman diagram rules, microscopic mean-field theories (Hartree-Fock and Kohn-Sham theories, natural orbitals), many-body perturbation theory, large-scale diagonalization methods, coupled-cluster theory, quantum computing algorithms, quantum machine learning algorithms and Green's function approaches.

Learning outcome

After this course you should :

  • be able to apply these methods to selected physical systems.
  • have a clear understanding of central many-body methods and their strengths and weaknesses.
  • understand the role of many-body correlations starting from various mean field approaches.
  • be able to use second quantization to develop many-body contributions.
  • be able to develop smaller programs that implement central many-body methods.


Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

Nordic citizens and applicants residing in the Nordic countries may apply to take this course as a single course student.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

To be eligible for this course you must be admitted to one of the following master's degrees:

The course is also available for exchange students.


Recommended previous knowledge

A good background in mathematics is needed.

The course is based on assigned self studies and four projects. There are no regular lectures. Meetings every two weeks (lasting an hour or two) are arranged in order to monitor progress and discuss projects and exercises.


  • Four project assignments that each is given 20% weight in the final grading (80% together).
  • A final oral exam that is given 20% weight in the final grading of the course.

Examination support material

No examination support material is allowed.

Language of examination

You may write your examination paper in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Explanations and appeals

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.

Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.

Withdrawal from an examination

It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.

Exam attempts in FYS-KJM4480 – Quantum mechanics for many-particle systems (discontinued), FYS-KJM9480 – Quantum mechanics for many-particle systems (discontinued) or FYS9480 – Quantum mechanics for many-particle systems (discontinued) count as exam attempts in FYS4480 – Quantum mechanics for many-particle systems (discontinued).

Special examination arrangements

The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
