Casimir力的同位素效应

Isotope effect on the Casimir force

Lanyi Xie, Fuwei Yang, Bai Song

摘要:

卡西米尔力的同位素依赖性是探索新物理学和推动微米和纳米级新技术的关键,但在很大程度上尚未探索。2002年,金属的同位素效应估计为10^(-4)-超出实验分辨率的数量级。在这里,通过使用Lifshitz理论,我们揭示了一个显着的同位素效应超过10^(-1)的极性氘。这种效应是由同位素质量引起的带心光学声子的谱线位移引起的,并且对谱线宽度不敏感。我们进行数值分析的虚频和实频轴,并推导出预测同位素效应的解析公式。

英文摘要:

Isotopic dependence of the Casimir force is key to probing new physics and pushing novel technologies at the micro and nanoscale, but is largely unexplored. In 2002, an isotope effect of 10^(-4) was estimated for metals -- orders of magnitude beyond the experimental resolution. Here, by employing the Lifshitz theory, we reveal a significant isotope effect of over 10^(-1) for polar dielectrics. This effect arises from the isotope-mass-induced line shift of the zone-center optical phonons and is insensitive to the linewidth. We perform numerical analyses on both the imaginary and real-frequency axes, and derive analytical formulas for predicting the isotope effect.
