Abstract
ABSTRACTWe study the properties of the charge distribution (polarization) of a 4-quantum dot square cell with two electrons, induced or modified by the coupling to a single quantized mode field. The effect of the relevant parameters (tunneling between dots, the amplitude of the electron-cavity interaction, cavity frequency) is investigated in the properties of polarization of the two-electron fundamental states. We further investigate the effects of asymmetry in the electron-cavity interaction in each dot and evaluate the modification to the dynamic evolution of the polarization. We find that there is a range of values of the asymmetry for which the polarization is improved. This suggests that an optimization of the coupling of the quantum dot cell with its environment may yield more reliable and stable operation.
