Density-functional theory of quantum wires and dots in a strong magnetic field.
We study the competition between the exchange and the direct Coulomb interaction near the edge of a two-dimensional electron gas in a strong magnetic field using density-functional theory in a local approximation for the exchange-energy functional. Exchange is shown to play a significant role in reducing the spatial extent of the compressible edge channel regions obtained from an electrostatic ...

متن کاملDensity Functional Theory of Spin-Polarized Disordered Quantum Dots
Using density functional theory, we investigate fluctuations of the ground-state energy of spin-polarized, disordered quantum dots in the metallic regime. To compare to experiment, we evaluate the distribution of addition energies and find a convolution of the Wigner-Dyson distribution, expected for noninteracting electrons, with a narrower Gaussian distribution due to interactions. The third m...
متن کاملDensity-functional theory simulation of large quantum dots
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. Here an efficient method for the simulation of quantum dots using density-function theory is developed; it includes the particlein-the-box representation of the Kohn-Sham orbitals, an efficient conju...
متن کاملSpin-Density-Functional Theory of Circular and Elliptical Quantum Dots
Using spin-density-functional theory, we study the electronic states of a two-dimensional parabolic quantum dot with up to N = 58 electrons. We observe a shell structure for the filling of the dot with electrons. Hund’s rule determines the spin configuration of the ground state, but only up to 22 electrons. At specific N , the ground state is degenerate, and a small elliptical deformation of th...
