✦ Synopsis

We discuss results of spin density functional calculations for lateral GaAs -AZGaAs quantum dots in the regime of electron number N N 100. We present typical results

showing the evolution of the total dot polarization as a gate voltage Vg is swept and the electron number increases. We show that occasional collapse of the spin polarization occurs and we note that these values of N "scarred" eigenstates at the Fermi surface.

are characterized by the presence of strongly

In this chapter we discuss various types of spin interaction in quantum dots. This involves spins from electrons and holes, as well as nuclear spins. The interaction of electrons includes the dipolar interaction of their spins as well as the Coulomb exchange interaction, which is an effective spin-s
