Chaire de théorie de la matière condensée

The general aim is to explore novel quantum states of matter induced by strong correlations. This research relies on the analytical and numerical investigation of lattice models of low-dimensional quantum magnetism in the presence of competing interactions or frustration. One of the long-standing open issue in the field is to identify the nature of the quantum spin liquid ground state of the spin-1/2 kagome antiferromagnet. More generally, the goal is to identify simple but realistic models that realize different types of quantum spin liquids (nematic, algebraic, chiral, etc.).
