Quantum dot properties in a strong magnetic field

We present a quasiclassical approach to few-electron quantum dots in strong magnetic fields based on the notion of a collectively rotating Wigner molecule. A quasiclassical many-particle wave function is derived and illustrated by its application to a two-electron quantum dot. In particular, we calculate the density-current correlation function (conditional current) and show that the Wigner crystal in high magnetic fields may be visualized as an ordered system of current vortices.
