Individual Molecules as efficient mOtion detectOrs and actuators of Nano-oscillators (IMOON) – IMOON

Carbon nanotube (CNT) based resonators hold the records in force and mass sensitivities, thanks to their small masses. However, the transduction of their vibrations into measurable electrical or optical signals is a challenging task. A promising way to detect and have control over such a resonator is to couple it with a well-known quantum system whose state can then be accurately measured. We propose the use of single fluorescent molecules displaying a strong Stark effect as an efficient tool to detect and manipulate the vibrations of a CNT oscillator attached to an AFM tip through the electrical field it creates. Laser driving of the molecule strongly coupled to the nanotube will allow efficient cooling of the oscillator and topological activation of its vibration modes. In addition, we will show that a CNT oscillator is the tool of choice for fast manipulation, by the Stark effect, of the entanglement of molecules coherently coupled by the dipole-dipole interaction.
