• I am interested in novel phases and properties in condensed matter and cold atom systems, including unconventional generalization of magnetism, orbital physics in transition metal oxides, superconductivity, spin-orbit coupling and spintronics, excitons, quantum phase transitions and criticality, strongly correlated bosonic and fermionic systems with cold atoms, and numerical algorithms for two dimensional quantum systems.

• Dr. Congjun Wu awarded Sloan Research Fellow (2008)
• Dr. Wu will receive a grant of $50,000 over a two year period.
  The Sloan Research Fellowships support the work of exceptional young researchers early in their academic careers, and often at pivotal stages in their work," says Paul L. Joskow, President of the Alfred P. Sloan Foundation.
  The Sloan Research Fellowships have been awarded since 1955. Wu is studying novel phases and properties in various fields of condensed matter physics, including metal-insulator transitions, magnetism and superconductivity, and quantum computation.
