0.1 ~ 0.9微米Casimir力的精密测量
Precision Measurement of the Casimir Force from 0.1 to 0.9 microns
摘要：
我们用原子力显微镜对直径为196微米的金属球与平板之间的卡西米尔力进行了精确测量。对于0.1至0.9微米的板-球分离测量力。实验结果与目前的理论计算，包括有限的电导率，粗糙度和温度的修正是一致的。理论和实验之间的均方根平均偏差为1.6 pN，对应于最小分离时的1%偏差。
英文摘要：
We have used an atomic force microscope to make precision measurements of the Casimir force between a metallized sphere of diameter 196 microns and flat plate. The force was measured for plate-sphere separations from 0.1 to 0.9 microns. The experimental results are consistent with present theoretical calculations including the finite conductivity, roughness, and temperature corrections. The root mean square average deviation of 1.6 pN between theory and experiment corresponds to a 1% deviation at the smallest separation.
