Simulating electron-vibron energy transfer with quantum dots and resonators

Physical review. B./Physical review. B, vol. 110

Abstract

Quantum dot arrays offer a natural representation of the interacting $\ensuremath{\pi}$-electron system of small hydrocarbon molecules. This paper proposes an extension of quantum dot simulators to include also the molecular vibrational modes represented by single-mode microwave resonators coupled capacitively to the quantum dots. The authors calculate the gate-tunable energy transfer from a voltage-biased triple quantum dot system to a single damped resonator mode and find a pronounced maximum near an interference node in the electrical current.
