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…
Electron Transport Through Molecules: Gate Induced Polarization and Potential Shift
San-Huang Ke, Harold U. Baranger, Weitao Yang
We analyze the effect of a gate on the conductance of molecules by separately evaluating the gate-induced polarization and the potential shift of the molecule relative to the leads…
Contact Atomic Structure and Electron Transport Through Molecules
San-Huang Ke, Harold U. Baranger, Weitao Yang
Using benzene sandwiched between two Au leads as a model system, we investigate from first principles the change in molecular conductance caused by different atomic structures arou…
Molecular Conductance: Chemical Trends of Anchoring Groups
San-Huang Ke, Harold U. Baranger, Weitao Yang
Combining density functional theory calculations for molecular electronic structure with a Green function method for electron transport, we calculate from first principles the mole…
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…
