DESCRIPTION:Schrodinger's equation has been known for more than 90 years\,
  yet many pressing questions in electronic structure theory remain unanswe
 red. Quantum Chemistry is a successful field: the weak correlation problem
  has been solved\; we can get "the right answer for the right reason" at r
 easonably low polynomial computational cost instead of the combinatorial e
 xpense of brute force approaches. Despite many advances\, however\, the so
 -called strong correlation problem\, where the chemist's molecular orbital
  picture breaks down\, remains open\, particularly for large molecules and
  solids. This seminar will address challenges and progress on the treatmen
 t of strong correlation\, and its connection with quantum symmetries and d
 egeneracy. Methods developed in our research group for strong correlation 
 will be discussed\, and applications to carbon nanostructures will be pres
 ented.
