The quantum dynamics of a nanomechanical resonator coupled to two quantum dots

Abstract

We investigate the quantum dynamics of a system composed of two initially excited closely-spaced quantum dots fixed on a quantum mechanical resonator. The system is submitted to environmental effects and obeys the conditions for Dicke-type collective interactions. We analytically solve the system dynamics and compare it to a single-quantum-dot case, in order to identify the inside mechanics of the influence of the quantum dot collective interaction to the dynamics of the mechanical resonator’s phonon field.
