Theory of Optomechanics, the cavity, mechanical dissipation (thermal decoherence), dilution technique, the (double) optical spring, quantum back-action, phase-induce back-action noise, and Raman decoherence. Especially, the dilution technique due to the gravitational and optical potential is explained in detail, because itacrimony 发表于 2025-3-27 14:51:47

Optical Torsional Spring,action acting on the massive objects beyond the Planck mass (.g) had not yet been observed because strong thermal fluctuating forces induced by the environment usually dominate measurements. To reduce the environmental noise, making the pendulum is suitable for allowing the mirror to be isolated froPatrimony 发表于 2025-3-27 22:49:19
Experimental Setup, source, calibration method, detection and vacuum system. Figure . shows the displacement noise due to the quantum back-action that sets our goal of sensitivity in displacement measurement. At the resonant frequency of the pendulum (130 Hz is supposed), the displacement noise is approximately . m/..污点 发表于 2025-3-28 02:25:24
Experimental Results,The origin of quantum back-action is momentum transferred to the mirror by light upon its reflection. Concerning the coherent light, the photon number fluctuates according to a Poisson distribution, which caused the radiation pressure fluctuation, termed radiation pressure shot noise (RPSN).

The Future,e standard quantum limit (SQL) for continuous force (displacement) measurement using the 5-mg pendulum. For these purposes, more higher Q-value pendulum than that developed in this thesis (suspended by the tungsten wire of 3 . in diameter) is necessary. Also, the passive cavity-assisted cooling is nHERTZ 发表于 2025-3-28 13:08:36
Conclusions,whose quantum component was estimated to be also larger than thermal fluctuating force at room temperature. The quantum back-action is one of the most significant issues to be investigated regarding the interferometric gravitational-wave (GW) detectors because it will directly limit the sensitivity
