Investigation of the exchange-correlation potential of functionals based on the adiabatic connection interpolation
E. Fabiano, S. Śmiga, S. Giarrusso +4
We have studied the correlation potentials produced by various adiabatic connection models (ACM) for several atoms and molecules. The results have been compared to accurate referen…
Strong-interaction limit of an adiabatic connection in Hartree-Fock theory
Michael Seidl, Sara Giarrusso, Stefan Vuckovic +2
We show that the leading term in the strong-interaction limit of the adiabatic connection that has as weak-interaction expansion the Moeller-Plesset perturbation theory can be full…
Sum-rules of the response potential in the strongly-interacting limit of DFT
Sara Giarrusso, Paola Gori-Giorgi, Klaas J. H. Giesbertz
The response part of the exchange-correlation potential of Kohn-Sham density functional theory plays a very important role, for example for the calculation of accurate band gaps an…
Response potential in the strong-interaction limit of DFT: Analysis and comparison with the coupling-constant average
Sara Giarrusso, Stefan Vuckovic, Paola Gori-Giorgi
Using the formalism of the conditional amplitude, we study the response part of the exchange-correlation potential in the strong-coupling limit of density functional theory, analys…
Assessment of interaction-strength interpolation formulas for gold and silver clusters
S. Giarrusso, P. Gori-Giorgi, F. Della Sala +1
The performance of functionals based on the idea of interpolating between the weak and the strong-interaction limits the global adiabatic-connection integrand is carefully studied…
