Query: Current density functional theory of quantum dots in a magnetic field   We present a study of ground state energies and densities of quantum dots in
a magnetic field, which takes into account correlation effects through the
Current-density functional theory (CDFT). The method is first tested against
exact results for the energy and density of 2 and 3 electrons quantum dots, and
it is found to yield an accuracy better than $ 3 \%. $ Then we extend the study
to larger dots and compare the results with available experimental data. The
orbital and spin angular momenta of the ground state, and the evolution of the
density profile as a function of the magnetic field are calculated.
Quantitative evidence of edge reconstruction at high magnetic field is
presented.
