Reduced Density Matrix Functional Theory- A suitable vehicle to import explicit correlations — •Ebad Kamil — Institute for Theoretical Physics, University of Goettingen, Goettingen, germany
A variational formulation for the calculation of interacting fermions system based on density matrix functional theory is presented. This formulation allows importing explicit many particle effects into standard density functional theory based calculations and also avoids ambiguities of double counting terms inherent to other approaches.
Local approximation for explicit correlations is introduced and the resulting impurity problem is solved using techniques of open quantum system.
