Effects of driving in carbon nanotube quantum dots — •Patrick Haughian — Université du Luxembourg

The field of nanomechanics has been seen to provide a toolbox to investigate non-classical states of matter. In particular, past work has explored the interplay between photonic and vibronic degrees of freedom in engineering interesting photon states. More recently, the transport properties of quantum dots with additional electron-vibron interaction have been investigated. The case of strong interaction features significant suppression of the conductance through those systems in what is known as Franck-Condon blockade.

Our present efforts consist of analyzing such an electromechanical system, making use of theoretical techniques familiar from the treatment of optomechanical settings. Here, we want to profit from recent developments in engineering carbon nanotubes as quantum dots to control the parameters of the system. This undertaking provides a novel interface between electronic and vibronic systems, allowing us to exhibit non-classical vibron states, with possible uses in measurement setups and in exploring the quantum behavior of macroscopic systems.
