Quantum spin liquids in frustrated magnets

Samuel Bieri

Quantum spin liquids are fascinating phases in quantum magnetism. Broad theoretical advances, and fast progress in materials science have significantly advanced the field in recent years. After a general introduction to the subject, I will talk about the projective symmetry group approach to the problem of classification of such exotic phases. In a second part, I will present work on the theory for the kapellasite material, a spin S=1/2 Heisenberg antiferromagnet on the kagome lattice. Finally, I will discuss a highly intriguing phase that was recently characterized in the triangular spin S=1 compound BaNiSbO. SB et al, PRB 93, 094437 (2016). SB et al, PRB 92, 060407(R) (2015). B.
