摘要:

无论是有意引入以控制粒子和宏观物体,例如捕获或冷却,还是由中性物体中电荷的量子和热波动引起,导致附近机械部件之间不必要的静摩擦,电磁相互作用在许多自然发生的过程和技术中发挥着重要作用。本文综述了近年来在光力学和量子涨落力的理解和实验观测方面的进展。虽然这两种效应都是由电磁动量的交换引起的,但它们的起源却截然不同,无论是真实的还是虚拟的光子,都导致了不同的物理表现和设计原理。具体来说,我们描述了最近的预测和测量的吸引力和排斥力的光学机械力,基于键合和反键的倏逝波的相互作用,以及预测的修改,甚至排斥纳米结构体之间的卡西米尔力。最后,我们讨论了潜在的影响和相互作用,这些力量在新兴的实验制度的微机械设备。

英文摘要:

Whether intentionally introduced to exert control over particles and macroscopic objects, such as for trapping or cooling, or whether arising from the quantum and thermal fluctuations of charges in otherwise neutral bodies, leading to unwanted stiction between nearby mechanical parts, electromagnetic interactions play a fundamental role in many naturally occurring processes and technologies. In this review, we survey recent progress in the understanding and experimental observation of optomechanical and quantum-fluctuation forces. Although both of these effects arise from exchange of electromagnetic momentum, their dramatically different origins, involving either real or virtual photons, lead to different physical manifestations and design principles. Specifically, we describe recent predictions and measurements of attractive and repulsive optomechanical forces, based on the bonding and antibonding interactions of evanescent waves, as well as predictions of modified and even repulsive Casimir forces between nanostructured bodies. Finally, we discuss the potential impact and interplay of these forces in emerging experimental regimes of micromechanical devices.
