对“中性物体上的普遍热辐射阻力”一文的评论
Comment on "Universal Thermal Radiation Drag on Neutral Objects"
摘要：
在最近的一封信[物理。91，220801（2003）]，V. Mkrtchian和同事计算了作用在运动物体上的辐射压力，假设电磁场的温度为$T,$，速度远小于$c.$。他们考虑了导体和导体，并将该效应与Casimir耗散力联系起来。在这里，我们声称，他们的方法可能只适用于瑞利-甘茨散射制度，这对应于非常小的粒子和/或电磁稀薄介质。此外，我们认为，他们的解释卡西米尔效应是误导，因为真空涨落没有贡献（隐含假设）制度的匀速运动。
英文摘要：
In a recent letter [Phys. Rev. Lett. 91, 220801 (2003)], V. Mkrtchian and co-workers calculated the radiation pressure force on a moving body, assuming the electromagnetic field to be at temperature $T,$ and the velocity to be much smaller than $c.$ They considered both dielectrics and conductors, and related the effect to Casimir dissipative forces. Here we claim that their approach may only apply in the Rayleigh-Ganz scattering regime, which corresponds to very small particles and/or electromagnetically rarefied media. Moreover, we argue that their interpretation in terms of the Casimir effect is misleading, since vacuum fluctuations do not contribute in the (implicitly assumed) regime of uniform motion.
