Abstract
The possibility of confining two interacting electrons in a magnetic quantum dot is investigated. Confinement is possible if the energy of two electrons localised inside the dot is less than the energy of two non-interacting electrons; one localised in the centre of the dot and one localised an infinite distance from the centre. Numerical results for a GaAs dot indicate regions where confinement is possible as a function of magnetic dot radius and confinement field strength. The confinement is enhanced if an external magnetic field is applied or in an InSb dot. Results for the electron density, pair distribution and pair correlation functions are also presented.
