摘要

对称是暗能量理论引入的光标量场之一,当它与物质耦合时,被认为会改变引力。然而,由于传统测量方法在高密度环境中具有屏蔽特性,对称场的检测具有挑战性。在本文中,我们提出了一种利用悬浮光学机械系统对对称参数设置约束的方案,在该系统中,纳米球作为测试质量耦合到光学腔。通过测量探针传输频谱的频移,我们可以通过计算对称诱导的影响来为我们的方案建立约束条件。与目前基于力的探测方法相比,这些改进的约束条件提高了1到3个数量级,为暗能量探测提供了新的机会。

Constraining symmetron fields with a levitated optomechanical system
The symmetron, one of the light scalar fields introduced by dark energy theories, is thought to modify the gravitational force when it couples to matter. However, detecting the symmetron field is challenging due to its screening behavior in the high-density environment of traditional measurements. In this paper, we propose a scheme to set constraints on the parameters of the symmetron with a levitated optomechanical system, in which a nanosphere serves as a testing mass coupled to an optical cavity. By measuring the frequency shift of the probe transmission spectrum, we can establish constraints for our scheme by calculating the symmetron-induced influence. These refined constraints improve by 1 to 3 orders of magnitude compared to current force-based detection methods, which offer new opportunities for the dark energy detection.

期刊介绍: Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
