摘要：

The dispersion relations of the collective modes of an optically created two-dimensional spin-polarized electron plasma, treated as a confined spin-polarized electron gas, are calculated. These exhibit many significant qualitative differences from their spin-unpolarized counterparts, such as emergence of the intrasubband spin wave and splitting of the intersubband spin waves and the longitudinal spin-density oscillations.
