A correct prediction of the thermal noise spectrum is crucial to design properly gravitational wave detectors which are intrinsically limited by this kind of fluctuation. The off-resonance slope of the spectrum can be predicted using the fluctuation-dissipation theorem and it must be consistent and compatible with the spectrum obtained through the normal mode representation. We investigate this comparison leading to a deeper understanding of the thermal noise prediction tools.

Abstract
A correct prediction of the thermal noise spectrum is crucial to design properly gravitational wave detectors which are intrinsically limited by this kind of fluctuation. The off-resonance slope of the spectrum can be predicted using the fluctuation-dissipation theorem and it must be consistent and compatible with the spectrum obtained through the normal mode representation. We investigate this comparison leading to a deeper understanding of the thermal noise prediction tools.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
