Quantum Magnetism
Lecture
Course number 112322
Fri, 8-10, IG1 seminar room 718
Content:
This course introduces the theoretical foundations of quantum magnetism, from microscopic models such as the Hubbard and Heisenberg Hamiltonians to effective interactions including spin–orbit coupling, anisotropies, and Dzyaloshinskii–Moriya exchange. Methods such as spin-wave theory, Green’s functions, and linear response are developed to describe quantum and thermal fluctuations, excitations, and response functions. Connections to experiments (inelastic neutron and x-ray scattering, transport) are highlighted. The final part of the course explores current research topics including magnetic symmetries, altermagnetism, frustration, spin nematics, spin liquids, and topological spin excitations.
