SUMMARY:Non-classical noise in quantum optomechanical systems\, R. G. 
 Herb Condensed Matter Seminar\, Aashish Clerk\, McGill University
DESCRIPTION:A key goal in the fields of quantum optomechanics and elec
 tromechanics is to measure and hopefully control truly quantum behavio
 ur in a "large" mechanical resonator.  In this talk\, I will start by 
 giving a quick introduction to these two rapidly growing fields.  I wi
 ll then discuss recent experimentally-motivated theoretical work which
  calculates the full statistics of low-frequency energy fluctuations o
 f a driven\, quantum resonator.  Surprisingly\, these fluctuations are
  highly non-classical: they are most naturally described by a quasi-pr
 obability distribution\, which can be negative.  Somewhat surprisingly
 \, this effect has a close relationship to the statistics of electroni
 c charge transfer (so-called "full counting statistics") in mesoscopic
  superconducting conductors.  I will discuss how these effects might b
 e measured\, and how they represent a kind of non-classical behaviour 
 similar to the violation of a Leggett-Garg inequality.  While the emph
 asis is on phonons\, our results apply equally as well to the photon f
 luctuations of a driven cavity.
