Interactions and Broken Time-Reversal Symmetry in Chaotic Quantum Dots
Denis Ullmo, Hong Jiang, Weitao Yang +1
When treating interactions in quantum dots within a RPA-like approach, time-reversal symmetry plays an important role as higher-order terms -- the Cooper series -- need to be inclu…
Interaction Effects in the Mesoscopic Regime: A Quantum Monte Carlo Study of Irregular Quantum Dots
Amit Ghosal, C. J. Umrigar, Hong Jiang +2
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 Mo…
Landau Fermi Liquid Picture of Spin Density Functional Theory: Strutinsky Approach to Quantum Dots
Denis Ullmo, Hong Jiang, Weitao Yang +1
We analyze the ground state energy and spin of quantum dots obtained from spin density functional theory (SDFT) calculations. First, we introduce a Strutinsky-type approximation, i…
Electron-Electron Interactions in Isolated and Realistic Quantum Dots: A Density Functional Theory Study
Hong Jiang, Denis Ullmo, Weitao Yang +1
We use Kohn-Sham spin-density-functional theory to study the statistics of ground-state spin and the spacing between conductance peaks in the Coulomb blockade regime for both 2D is…
An Efficient Algorithm for Density Functional Theory Simulation of Large Quantum Dot Systems
Hong Jiang, Harold U. Baranger, Weitao Yang
Kohn-Sham spin-density functional theory provides an efficient and accurate model to study electron-electron interaction effects in quantum dots, but its application to large syste…
Spin and Conductance-Peak-Spacing Distributions in Large Quantum Dots: A Density Functional Theory Study
Hong Jiang, Harold U. Baranger, Weitao Yang
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…
