摘要:

本文报道了在微米量级上对非牛顿引力的实验测试。为了在实验上减去卡西米尔力和静电力背景,通过使用软悬臂梁感测金球和密度调制源质量之间的横向力来执行差力测量。电流灵敏度受到贴片静电力的限制,通过二维(2D)力映射进一步提高。初步的结果设置在这个范围内的汤川型力的模型独立的约束。

英文摘要:

We report an experimental test of non-Newtonian gravitational forces at mi- crometer range. To experimentally subtract off the Casimir force and the electrostatic force background, differential force measurements were performed by sensing the lateral force between a gold sphere and a density modulated source mass using a soft cantilever. The current sensitivity is limited by the patch electrostatic force, which is further improved by two dimensional (2D) force mapping. The preliminary result sets a model independent constraint on the Yukawa type force at this range.
