A BCS-like variational wave-function, which is exact in the infinite field
limit, is used to study the interplay among Zeeman energies, lateral
confinement and particle correlations induced by the Coulomb interactions in
strongly pumped neutral quantum dots. Band mixing effects are partially
incorporated by means of field-dependent masses and g-factors. The spin
polarization and the magneto-luminescence are computed as functions of the
number of electron-hole pairs present in the dot and the applied magnetic
field.Comment: To appear in Phys. Rev.
