"The sound of tiny guitars approaching the quantum regime"

Kivonat: Mechanics has historically played a pivotal role in science by
providing the basis for classical physics. Today, with the advent of
nanoscale mechanical devices combined with quantum electronic devices, we are
witnessing a renaissance in the field of mechanics. After an introduction on
the mesoscopic physics of nanomechanical resonators, I will discuss our
recent advances on mechanical resonators based on carbon nanotubes. The
nanotube in these devices vibrates as a guitar string. Single-electron
tunneling enables coupling the mechanical vibrations to electrons by a large
amount. I will show how to use this coupling to create a nonlinear mechanical
oscillator approaching the quantum regime, where the resulting quantum energy
levels of the mechanical oscillator are no longer evenly spaced. Using
mechanical nanotubes hosting multiple quantum dots, we expect that our
approach may enable the realization of a mechanical qubit and a quantum
simulator of quantum matters featuring strong electron-phonon correlations.
