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…
Scrambling and Gate Effects in Realistic Quantum Dots
Hong Jiang, Denis Ullmo, Weitao Yang +1
We evaluate the magnitude of two important mesoscopic effects using a realistic model of typical quantum dots. ``Scrambling'' and ``gate effect'' are defined as the change in the s…
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…
Conjugate-Gradient Optimization Method for Orbital-free Density Functional Calculations
Hong Jiang, Weitao Yang
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 ac…
