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...

Long-range interaction between polar Rydberg atoms

The most attractive and the most repulsive potential-energy curves for interaction between two Rydberg atoms in a broad superposition of internal angular momentum states are studied. The extreme Stark states have the largest dipole moments and provide the dominant contribution to the interaction which is then expressed as a long-range expansion involving the permanent multipole moments Qj of ea...

Long-Range Interaction Models and Yangian Symmetry

The generalized Sutherland-Römer model and Yan models with internal spin degree are formulated in terms of both the Polychronakos’ approach and RTT relation associated to Yang-Baxter equation in consistent way. The Yangian symmetry is shown to generate both the models. We finally introduce the reflection algebra K(u) to long range interaction models. PACS numbers: 05.30.-d, 03.65.Fd, 05.50.+q
