Properties of short-range and long-range correlation energy density functionals from electron-electron coalescence

The combination of density-functional theory with other approaches to the many-electron problem through the separation of the electron-electron interaction into a short-range and a long-range contribution is a promising method, which is raising more and more interest in recent years. In this work some properties of the corresponding correlation energy functionals are derived by studying the ele...

Combining long-range configuration interaction with short-range density functionals

A density functional for short-range electron–electron interaction recently developed by one of us, has been implemented into a multi-reference configuration-interaction code with explicit treatment of long-range interaction only. Possible Ž . Ž advantages of such an approach are discussed, using as examples some closed-shell atoms Be, Ne and diatomics H , Li , 2 2 . C , N , F . q 1997 Publishe...
