Adventures in Strong Correlation
|
|
Quantum Chemistry is a mature field. Progress in the last 50 years has been fantastic. The weak correlation problem has been conquered by coupled cluster theory, but strong correlation remains pervasive and problematic. Many practical applications are hindered by this obstacle. Of course, it is not surprising that after almost 100 years of Schrodinger equation, only the most difficult problems are left. In the past decade, my research group has focused on strong correlation, and in this talk, I will discuss our recent efforts to tackle it. Our current approach centers around the somewhat whimsical hope that using a non-canonical duality, we can convert strongly correlated electrons into weakly correlated ones. Many-body string operators, whose matrix elements can be obtained with polynomial cost, play a central role in our approach. I will present proof of principle applications of the theory to model systems where the interaction strength can be easily tuned.
