摘要:

我们已经完成了精确的实验测定的Casimir压力之间的两个镀金的平行板通过微机械振荡器。与所有先前的Casimir效应实验相比,其中仅在最短分离处实现小的相对误差(从1%到15%变化),我们的最小实验误差($\sim 0.5$ %)在从170 nm到300 nm的宽分离范围内以95%置信度实现。我们已经制定了一个严格的实验和理论的比较,而不诉诸以前使用的均方根偏差,这在文献中已被批评的discovery程序。这使我们能够区分不同的竞争理论的热卡西米尔力,并解决了热力学难题所产生的应用Lifshitz理论的实际金属。我们的研究结果导致一个更严格的方法来获得额外的维物理和其他扩展的标准模型预测的假设的长程相互作用的约束。特别是,在95%的置信度下,在很宽的相互作用范围内,对非牛顿引力的约束被加强了20倍。

英文摘要:

We have performed a precise experimental determination of the Casimir pressure between two gold-coated parallel plates by means of a micromachined oscillator. In contrast to all previous experiments on the Casimir effect, where a small relative error (varying from 1% to 15%) was achieved only at the shortest separation, our smallest experimental error ($\sim 0.5$%) is achieved over a wide separation range from 170 nm to 300 nm at 95% confidence. We have formulated a rigorous metrological procedure for the comparison of experiment and theory without resorting to the previously used root-mean-square deviation, which has been criticized in the literature. This enables us to discriminate among different competing theories of the thermal Casimir force, and to resolve a thermodynamic puzzle arising from the application of Lifshitz theory to real metals. Our results lead to a more rigorous approach for obtaining constraints on hypothetical long-range interactions predicted by extra-dimensional physics and other extensions of the Standard Model. In particular, the constraints on non-Newtonian gravity are strengthened by up to a factor of 20 in a wide interaction range at 95% confidence.
