Coating thermal noise for arbitrary shaped beams [PDF]
, 2006 Advanced LIGO's sensitivity will be limited by coating noise. Though this noise depends on beam shape, and though nongaussian beams are being seriously considered for advanced LIGO, no published analysis exists to compare the quantitative thermal noise ...

Deviation from the normal mode expansion in a coupled graphene-nanomechanical system [PDF]
, 2016 We optomechanically measure the vibrations of a nanomechanical system made of a graphene membrane suspended on a silicon nitride nanoresonator. When probing the thermal noise of the coupled nanomechanical device, we observe a significant deviation from ...
