DESCRIPTION:Speaker: Edward Laird\nhosted by Georgios Katsaros\nAbstract: N
 anomechanical resonators allow the boundary between classical and quantum 
 motion to be explored and exploited. Suspended carbon nanotubes\, vibratin
 g like tiny guitar strings\, are an outstanding experimental material beca
 use they combine low mass (leading to large zero-point motion)\, high spec
 ific stiffness (leading to large phonon energy)\, and high quality factor 
 (leading to long coherence times). Until now\, most measurements relied on
  electrical transport through the device\, but optomechanical experiments 
  exploiting resonant capacitive coupling to the nanotubes displacement  pr
 omise higher sensitivity and the possibility to manipulate the mechanical 
 state in new ways. I will show optomechanical measurements using a radio-f
 requency electrical circuit as a tuneable detector for the nanotubes vibra
 tions. I will discuss potential for using nanotube springs as ultra-sensit
 ive force transducers for nanoscale magnetic resonance. Finally\, I will p
 resent a proposal to verify quantum behaviour in a suspended resonator by 
 constructing an on-chip interferometer in which the entire nanotube\, cont
 aining a million nucleons\, forms the particle under test.
