Two electrons in a quantum dot: a semiclassical approach
Abstract
The spectra of two electrons in a parabolic quantum dot in a magnetic field are obtained using the WKB approximation. No restrictions are imposed on the value of the electron-electron interaction. A simple approximation allowing an exact solution to be obtained for the interaction between two electrons in a quantum dot is proposed. It reproduces all of the qualitative features of the two-electron spectrum. Quantitatively, it is in good agreement with the WKB solution for the range of parameters of experimental interest.
