Abstract:For coupled quantum dots formed in a single InAs quantum wire, we use the variational Heitler-London method to obtain the single- and two-particle ground state energies. We show the variational Heitler-London methods yield lower ground state energies than the conventional approach. We find that the exchange energy decreases as the wire diameter becomes smaller due to enhanced coulomb interaction in a quasi-one-dimensional system.
