Effect of electron-electron interaction and disorder potential on the localization of two-dimensional electrons in a strong magnetic field
A. A. Vasilchenko
The density functional theory is used to study the electronic structure of a quantum wire in a magnetic field. The Kohn-Sham equations are solved numerically for different values o…
A drop model of integer and fractional quantum Hall effects
A. A. Vasilchenko
We present a drop model for integer and fractional quantum Hall effects (FQHE). We show that the two-dimensional electron gas breaks up into regions with filling factors ν = 1 and…
Density-functional study of electronic structure of quantum dots in high magnetic fields
A. A. Vasilchenko
Density-functional theory is used to study the electronic structure of quantum dots in a magnetic field. New series of magic numbers are found for the total angular momentum of ele…
Spin polarization of electrons in quantum wires
A. A. Vasilchenko
The total energy of a quasi-one-dimensional electron system is calculated using density functional theory. It is shown that spontaneous ferromagnetic state in quantum wire occurs a…
