Quantum interactions between a laser interferometer and gravitational waves

摘要: LIGO’s detection of gravitational waves marks a first step in measurable effects general relativity on quantum matter. In their current operation, laser interferometer gravitational-wave detectors are already limited at high frequencies, and planned upgrades aim to decrease the noise floor level over wider bandwidth. This raises interesting idea what detector—or, more generally, an optomechanical system—may reveal about gravity beyond detecting from highly energetic astrophysical events, such as its versus classical nature. this paper we develop treatment interactions with detector. We show that recovers known equations motion limit for gravity, apply our formulation study system dynamics, particular focus implications quantization. Our framework can also be extended alternate theories ways which features manifest themselves system.
