Electronic structure via potential functional approximations
Attila Cangi, Donghyung Lee, Peter Elliott +2
The universal functional of Hohenberg-Kohn is given as a coupling-constant integral over the density as a functional of the potential. Conditions are derived under which potential-…
Leading corrections to local approximations
Attila Cangi, Donghyung Lee, Peter Elliott +1
For the kinetic energy of 1d model finite systems the leading corrections to local approximations as a functional of the potential are derived using semiclassical methods. The corr…
Potential Scaling in Density Functional Theory
Peter Elliott, Kieron Burke
Density scaling has a rich history in density functional theory, providing exact conditions for use in the construction of ever more accurate approximations to the unknown exchange…
Partition Density Functional Theory
Peter Elliott, Kieron Burke, Morrel H. Cohen +1
Partition density functional theory is a formally exact procedure for calculating molecular properties from Kohn-Sham calculations on isolated fragments, interacting via a global p…
