干涉仪对标量引力波的响应

Interferometer Response to Scalar Gravitational Waves

C. Corda, S. A. Ali, C. Cafaro

摘要:

最近有人提出,引力波(GWs)的磁分量与引力干涉仪频率响应函数的评估有关。在本文中,我们扩展的标量张量引力理论所产生的GWs的标量模式的磁分量的分析。在低频近似下,计算了地基干涉仪的响应函数。讨论了响应函数的电磁贡献的角度依赖性。最后,对于一个任意的频率范围内,两个测试质量之间的适当的距离计算和它的有用性在高频率限制的天基干涉仪被简要地考虑。

英文摘要:

It was recently suggested that the magnetic component of Gravitational Waves (GWs) is relevant in the evaluation of frequency response functions of gravitational interferometers. In this paper we extend the analysis to the magnetic component of the scalar mode of GWs which arise from scalar-tensor gravity theory. In the low-frequency approximation, the response function of ground-based interferometers is calculated. The angular dependence of the electric and magnetic contributions to the response function is discussed. Finally, for an arbitrary frequency range, the proper distance between two test masses is calculated and its usefulness in the high-frequency limit for space-based interferometers is briefly considered.
