Switching off energy decay channels in nanomechanical resonators Open
Energy decay plays a central role in a wide range of phenomena, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as a system leaking energy irreversibly into an environmental …

Graphene mechanical resonators coupled to superconducting microwave cavities Open
In recent years, mechanical resonators based on graphene have attracted considerable interest as nanoelectromechanical systems (NEMS). Graphene NEMSs allow for exceptional properties such as high mechanical strength, high frequencies and q…

Force sensitivity of multilayer graphene optomechanical devices Open
Mechanical resonators based on low-dimensional materials are promising for force and mass sensing experiments. The force sensitivity in these ultra-light resonators is often limited by the imprecision in the measurement of the vibrations, …

Switchable Coupling of Vibrations to Two-Electron Carbon-Nanotube Quantum Dot States Open
We report transport measurements on a quantum dot in a partly suspended carbon nanotube. Electrostatic tuning allows us to modify and even switch "on" and "off" the coupling to the quantized stretching vibration across several charge state…
