EnglishGround based gravitational wave detectors show extremely high displacement sensitivity which approaches the level set by the quantum limit. However a detection will likely be achieved at a low signal-to-noise ratio, making it mandatory to know the noise budget and statistics. The RareNoise project has pointed out a few mechanisms that cause the instruments to operate at non-equilibrium states. We argue that this aspect has not been given appropriate consideration and that it could alter the overall predicted performance of the detector. The large fluctuations of a non-equilibrium object often differ statistically from those studied at thermodynamic equilibrium. We present experimental and theoretical activity devised to further investigate this question.

| Abstract: | Ground based gravitational wave detectors show extremely high displacement sensitivity which approaches the level set by the quantum limit. However a detection will likely be achieved at a low signal-to-noise ratio, making it mandatory to know the noise budget and statistics. The RareNoise project has pointed out a few mechanisms that cause the instruments to operate at non-equilibrium states. We argue that this aspect has not been given appropriate consideration and that it could alter the overall predicted performance of the detector. The large fluctuations of a non-equilibrium object often differ statistically from those studied at thermodynamic equilibrium. We present experimental and theoretical activity devised to further investigate this question. |
