Introduction to Frustrated Magnetism
Frequency
Every 3 years
Summary
To provide an introduction to all aspects of the rapidly evolving field of frustrated magnetism: 1) New paradigms: spin liquids, spin ice, topological order, ... 2) Basic models and methods 3) Experimental realizations
Content
1) Introduction: definition and overview of frustration in magnetism
2) Basic models
3) Classical frustrated magnets: ground state degeneracy and ground state correlations
4) Order by disorder: ordering by thermal or quantum fluctuations
5) Spontaneous breaking of translational symmetry: valence-bond solids, magnetization plateaux
6) Broken SU(2) symmetry without magnetic order: nematic order
7) Spin liquids: Resonating-Valence Bond liquids, algebraic order, topological order
8) Conclusion: open issues and perpectives
