We investigate electronic excitations in GaAs–AlGaAs quantum dots by means of resonant inelastic light scattering in the presence of an external magnetic field Image . At magnetic field Image , we observe a series of discrete electronic excitations, namely, charge-density excitations (CDEImage ) and spin-density excitations (SDEImage ), in one and the same quantum dot sample. We find at finite ...
