DESCRIPTION:Speaker: Natalia Ares\nhosted by Georgios Katsaros\nAbstract: N
 anotubes are ideal for exploring the boundary between classical and quantu
 m motion\, combining low mass (large zero-point motion)\, high stiffness (
 large mode spacing)\, and high quality factor (long coherence times). I wi
 ll focus on mechanical displacement approaching the standard quantum limit
  near the phonon ground state. I will show sensitive optomechanical probin
 g of the vibrations of a suspended carbon nanotube at milliKelvin temperat
 ures [1\,2]. With quantum dots embedded in the carbon nanotube\, I will de
 monstrate the impact of electron tunnelling on the mechanical motion\, inc
 luding the excitation of self-oscillations. I will also discuss the feasib
 ility of experiments that\, combining electrical and mechanical degrees of
  freedom\, might enable a key capability for experiments on quantum thermo
 dynamics: direct measurements of work exchange in the quantum regime.Refer
