Orbital-free density functional theory as an extension of traditional Thomas-Fermi theory has attracted a lot of interest in the past decade because of developments in both more accurate kineticâ€¦ (More)

Kohn-Sham spin-density functional theory provides an efficient and accurate model to study electronelectron interaction effects in quantum dots, but its application to large systems is a challenge.â€¦ (More)

We use spin-density-functional theory to study the spacing between conductance peaks and the ground-state spin of 2D model quantum dots with up to 200 electrons. Distributions for different ranges ofâ€¦ (More)

We address the issue of accurately treating interaction effects in the mesoscopic regime by investigating the ground-state properties of isolated irregular quantum dots. Quantum Monte Carloâ€¦ (More)

The orbital-dependent correlation energy functional resulting from second order Kohn-Sham perturbation theory leads to atomic correlation potentials with correct shell structure and asymptoticâ€¦ (More)

When treating interactions in quantum dots within a random-phase-approximation sRPAd-like approach, time-reversal symmetry plays an important role as higher-order termsâ€”the Cooper seriesâ€”need to beâ€¦ (More)

The aim of this study was to determine whether the intraparietal sulcus plays a role in statistical calculations. Three conditions were employed, two experimental and one control. The control groupâ€¦ (More)
