用套顶传感器测量Casimir力

Measurement of the Casimir force with a ferrule-top sensor

P. Zuurbier, S. de Man, G. Gruca, K. Heeck, D. Iannuzzi

摘要:

我们提出了一个Casimir力的基础上,全光学套圈顶部传感器的设置。我们证明,该仪器可用于测量的Casimir力之间的梯度的金涂层的球体和金涂层的板与结果是可比的,通过类似的原子力显微镜实验所取得的。由于力传感器的单片设计(不需要任何光学三角测量读数)以及传感头上没有电子器件,该仪器代表了未来在工程条件下研究Casimir效应的重要一步,其中介入介质或环境条件可能不适合使用更标准的设置。

英文摘要:

We present a Casimir force setup based on an all-optical ferrule-top sensor. We demonstrate that the instrument can be used to measure the gradient of the Casimir force between a gold coated sphere and a gold coated plate with results that are comparable to those achieved by similar atomic force microscope experiments. Thanks to the monolithic design of the force sensor (which does not require any optical triangulation readout) and to the absence of electronics on the sensing head, the instrument represents a significant step ahead for future studies of the Casimir effect under engineered conditions, where the intervening medium or the environmental conditions might be unsuitable for the use of more standard setups.
