Symmetry restoration in mean-field approaches
J. A. Sheikh, J. Dobaczewski, P. Ring +2
The mean-field approximation based on effective interactions or density functionals plays a pivotal role in the description of finite quantum many-body systems that are too large t…
Fragmentation of the photoabsorption strength in neutral and charged metal microclusters
C. Yannouleas, R. A. Broglia, M. Brack +1
The line shape of the plasma resonance in both neutral and charged small sodium clusters is calculated. The overall properties of the multipeak structure observed in the photoabsor…
Coupling and Dissociation in Artificial Molecules
Constantine Yannouleas, Uzi Landman
We show that the spin-and-space unrestricted Hartree-Fock method, in conjunction with the companion step of the restoration of spin and space symmetries via Projection Techniques (…
Collective and independent-particle motion in two-electron artificial atoms
Constantine Yannouleas, Uzi Landman
Investigations of the exactly solvable excitation spectra of two-electron quantum dots with a parabolic confinement, for different values of the parameter R_W expressing the relati…
