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)
