  We present results on spin and charge correlations in two-dimensional quantum
dots as a function of increasing Coulomb strength (dielectric constant). We
look specifically at the orbital occupation of both spin and charge. We find
that charge and spin evolve separately, especially at low Coulomb strength. For
the charge, we find that a hole develops in the core orbitals at strong Coulomb
repulsion, invalidating the common segregation of confined electrons into an
inert core and active valence electrons. For excitations, we find a total
spin-projection $S_z = -1/2$ breaks apart into separate occupations of positive
and negative spin. This dissociation is caused by spin correlations alone.
Quantum fluctuations arising from long-range Coulomb repulsion destroy the spin
dissociation and eventually results in all orbitals carrying a negative spin.
