从随机引力波背景探测引力子

Gravitons probing from stochastic gravitational waves background

Hongguang Zhang, Xilong Fan, Yihui Lai

摘要:

量子引力是物理学中的一个挑战,引力子的存在是目前的首要问题。本文研究了引力子引起的量子噪声的可探测性。计算了压缩态中量子噪声的关联,但我们惊奇地发现,结果与Grishchuk等人和Parikh等人的结果一致,这意味着它们本质上是关于一件事:引力子的量子噪声.进一步的讨论表明,量子噪声应该从引力与探测器相互作用的首阶来完成。估计了压缩因子,并利用压缩因子得到了量子噪声的频谱形式为$Ω_0 \sim ν^{4+a_0 β+b_0}$。在与几种引力波探测器的灵敏度进行比较后,我们得出结论,量子噪声在未来是可以探测到的。

英文摘要:

Quantum gravity is a challenge in physics, and the existence of graviton is the prime question at present. We study the detectability of the quantum noise induced by gravitons in this letter. The correlation of the quantum noise in the squeezed state is calculated, but we are surprised to find that the result is the same as those from Grishchuk et.al. and Parikh et.al. This implies that they are essentially about one thing: the quantum noise from the gravitons. The further discussion shows the quantum noise should be completed from the leading order of the interaction between gravitation and the detector. The squeezed factor is estimated, and with it, the spectrum of the quantum noise is found to be of the form $Ω_0 \sim ν^{4+a_0 β+b_0}$. After comparing it to the sensitivities of several gravitational wave detectors, we conclude that the quantum noise is detectable in the future.
