DESCRIPTION:Strongly correlated systems are extremely difficult to simulat
 e with traditional electronic structure methods.  The most widely used tec
 hniques for simulating realistic materials lose their predictive power whe
 n strong electron correlations are present.  For example\, there remain ma
 ny open questions about the electronic properties of the high temperature 
 superconducting cuprate materials.\n\nRecent developed methods that can si
 mulate strong electron correlations\, have demonstrated remarkable progres
 s in tackling larger systems than previously thought possible. I intend to
  discuss one such method\, which is the adaptive sampling configuration in
 teraction technique (ASCI).  The ASCI technique cleverly explores determin
 ant space and very quickly finds the most important degrees of freedom for
  a given Hamiltonian system.  I will demonstrate the capabilities of ASCI 
 on strongly correlated molecular systems and discuss the potential for fut
 ure applications in solid state systems. \n
