    Laser-induced Interaction of Multilevel Quantum Dots

    No full text
    A theoretical model is developed for describing the laser-induced interaction of a pair of multilevel semi- conductor quantum dots. Spectral dependencies of interaction energy are calculated in dipole-dipole ap- proximation for a pair of CdSe quantum dots in a quasi-resonant laser field, for cases of two identical quantum dots and those with differing transition wavelengths. Interaction energy of pair of multilevel quantum dots in the long-wavelength potential well is much higher than that of pair of two-level quan- tum dots. The increase of difference of resonance wavelengths of two interacting quantum dots leads to decrease of the potential well depth
