论文摘要
在本文中，我们认为，即使有强烈的理论和经验原因期望在短距离内违反空间各向同性，但在短距离探测引力相互作用的现代设置尚未配置为测量这种空间各向异性。我们提出了对最新的扭转钟摆设计的简单修改，并在数值上证明，由于引力的大量空间 - 异位成分，同时抑制了信号，同时保持对短距离空间偏置的高灵敏度。我们使用Yukawa型和幂律型短距离校正重力融合了各向异性。所提出的差异扭转摆会显示能够对小引力各向异性进行敏感测量，并且所得的各向异性扭矩在很大程度上独立于基础短途修改的细节至重力。因此，如果对重力进行各向异性修改，则以任何理论（以任何形式的修改电势）进行了修改，则提议的设置提供了一种实用的检测方法。
In this paper we argue that, even though there are strong theoretical and empirical reasons to expect a violation of spatial isotropy at short distances, contemporary setups for probing gravitational interactions at short distances have not been configured to measure such spatial anisotropies. We propose a simple modification to the state-of-the-art torsion pendulum design and numerically demonstrate that it suppresses signals due to the large spatially-isotropic component of the gravitational force while maintaining a high sensitivity to short-range spatial anisotropies. We incorporate anisotropy using both Yukawa-type and power-law-type short-distance corrections to gravity. The proposed differential torsion pendulum is shown to be capable of making sensitive measurements of small gravitational anisotropies and the resulting anisotropic torques are largely independent of the details of the underlying short-distance modification to gravity. Thus, if there is an anisotropic modification to gravity, from any theory, in any form of the modified potential, the proposed setup provides a practical means of detecting it.
