Abstract
We show that the low-energy peak in the polarized resonant Raman spectra of quantum wires, which is commonly associated with “single particle excitations,” can be interpreted as a signature of intraband collective spin excitations. A broad maximum in the resonant depolarized spectra is predicted to exist above the frequency of the spin-density excitation, due to simultaneous but independent propagation of spin- and charge-density modes.Keywords
