Abstract
An exact solution for the density of electrons in a quantum dot with model quadratic interactions between the electrons is derived, taking into accoun t correlation effects between the electrons. These correlation effects give rise to oscillations in the density as a function of the radial distance f rom the center of trapping potential of the dot. Upon increasing the temper ature, the density profile smoothens and the oscillations vanish. (C) 1999 Elsevier Science Ltd. All rights reserved.
