Spin liquids: from frustrated magnets to quantum dimer models — •Frederic Mila — Institute of Theoretical Physics, Ecole Polytechnique Federale de Lausanne, BSP Unil, CH-1015 Lausanne (Switzerland)

The search for Resonating Valence Bond (RVB) spin liquids has been extremely active since the discovery of high temperature superconductivity in a family of cuprates and the proposal by Anderson that doping RVB spin liquids might lead to superconductivity. Very significant progress has been made recently on two fronts: 1) Experimentally, with the synthesis of compounds which seem to resist any kind of ordering down to the lowest accessible temperatures; 2) Theoretically, with the numerical proof that the Quantum Dimer Model on the triangular lattice has an RVB phase. In this talk, I will review both aspects of the field, and I will discuss the possible relationships between Quantum Dimer Models and realistic effective models of Mott insulators.
