Theory of strongly correlated electron systems

• Development of new techniques for strongly correlated systems

• Exotic ground states in quantum impurity systems
• Heavy fermion systems
• Combination of band structure calculations and strongly correlated methods in quantum impurity systems

Mesoscopic physics

• Non-equilibrium dynamics and transport in correlated systems

• Decoherence at low temperatures
• Correlation effects in quantum dots and other low-dimensional systems

Disorder and interaction in electronic systems

• Surface charge density oscillations
• Anderson localization in random optical systems:
  - Propagation and localization of classical waves in random media
  - Random lasers

Cold atoms

• Optical lattices, Bose Josephson junctions, merging of the condensates
