A two-pronged approach to electron correlation in RDMFT

Joshua Hollett
University of Winnipeg, Canada


In addressing the correlation problem of electronic structure theory, understanding and utility has been found in the partitioning of electron correlation into static and dynamic components [1]. Recently, we have taken this partitioning a step further in combining significantly different approaches to the correlation problem, density functional theory (DFT) and reduced density matrix functional theory (RDMFT), to separately capture both components of electron correlation [2]. I will discuss the key advantages of such an approach, along with, our recent progress in extending the method to open shells, and deriving an "on-top" density functional for dynamic correlation.
