Quantum Cluster Methods for Correlated Materials Sherbrooke, 6-8 Juillet 2005
Quantum Cluster Methods for Correlated Materials • Does the Hubbard model have a d-wave superconducting ground state? • What is the origin of the pseudogap in high-temperature superconductors? • When do stripes and other inhomogeneous phases appear? • How can we predict properties of materials with d and f electrons? (or cold atoms)
Quantum Clusters for Correlated Materials • One-particle properties : Experiment • ARPES (Shen, Damascelli) • Local DOS (Davis, Lupien) • Spin excitations : Experiment • Neutron (Greven)
