The problem of electromagnetic response and collective excitations in arrays of quantum wires and dots is solved taking into account electrodynamic (radiative) effects and the interwire (interdot) interaction. The radiative contribution ( ) to the total linewidth of collective modes is calculated. I
We review recent magneto-Raman experiments on electronic excitations in GaAs-AlGaAs quantum wires and dots. We observe simultaneously collective spin-density and charge-density excitations (SDEs and CDEs), and also single-particlelike excitations. In a magnetic ÿeld, the CDEs (magnetoplasmons) exhib
