| Abstract: | The features of the low-lying spectra of
four-body A+B-A+B-
systems have been deduced based on
symmetry. Using the method of few-body physics, we calculate the energy
spectra of A+B-A+B-
systems in a harmonic quantum dot. We find that the biexciton in a two-dimensional quantum dot may have other bound excited states and the quantum mechanical symmetry plays a crucial role in determining the energy levels and structures of the low-lying
states. |
