ABSTRACTWe study the dynamics of the charge distribution (polarization) in an array of four quantum dots located at the corners of a square. The array has two extra electrons in a neutralizing background. We take into account electron-phonon interaction effects using a quantum Markovian master equation approach. Results show that dissipative effects are determinant in the dynamical response of a quantum-dot cell close to a nearby driver cell with prescribed polarization varying with time. The response is shown to depend strongly on temperature.
