NFYK16002U Quantum Magnetism
MSc Programme in Physics
(focus is put differently from year to year but covers)
Classical magnetic order, different antiferromagnetic phases
Classical phase transitions and critical phenomena
Corrections to the classical picture of magnetism (spin wave theory, mean field theory, magnetic thermodynamics, high-temperature expansion)
Solvable non-frustrated quantum systems (1D Ising model, 1D Heisenberg chain, Small systems, exact diagonalization, 2D Ising square lattice)
Quantum phase transitions (1D Ising transverse field, General picture)
Frustration (2D triangular Ising, Anderson RVB,Spin glasses)
Experimental techniques (susceptibility, magnetization, heat capacity, Resonant magnetic x-ray scattering, polarized neutron scattering, muon spin rotation)
The students aquire an understanding of current solved and unsolved problems in many-body quantum mechanics, exemplified in quantum magnets. They also obtain an uderstanding of particular current topics as quantum phase transitions and frustration in magnetism.
The students become proficient with a number of theoretical methods, including mean-field theory, spin wave theory, high-temperature expansion, and exact diagonalization.
In addition, the students are capable of interpreting and modeling data from a number of experimental techniques, including susceptibility, heat capacity, and neutron scattering.

- 7,5 ECTS
- Type of assessment
- Written assignment, 4 weeksProject report, possibly 2-person groups. The students have 4 weeks (parallel to the teaching) to work on the project, which should be handed in in the exam week.
- Exam registration requirements
2 student presentations
- All aids allowed
- Marking scale
- passed/not passed
- Censorship form
- No external censorship
The course responsible plus one person.
Same as ordinary exam.
A student who has not fulfilled the exam registration requirements (2 presentations) must instead pass an oral test no later than 2 weeks before the re-exam date.
