Abstract :
We theoretically investigate nonlinear excitations in a double quantum dot (DQD). Here an antenna system couples with one of the quantum dots, and enhances the effective light-DQD interactions. It is found that a flexible and strong nonlinearity of the excitations in the coupled system. This nonlinearity is caused by quantum interferences due to the antenna-enhanced decay rates in the DQD and scattering paths in DQD.
