聚焦真空涨落

Focusing Vacuum Fluctuations

L. H. Ford, N. F. Svaiter

摘要:

研究了量子化光场真空模在抛物柱面镜上的聚焦。我们使用几何光学近似来计算焦点附近标量场和电磁场的能量密度和均方场平均值。我们发现,这些数量的增长作为一个反幂的距离的焦点。在原子上有一种吸引力Casimir-Polder力,它会把原子吸引到焦点上。对这种聚焦效应的一些估计表明,这种效应是可以观察到的。

英文摘要:

The focusing of the vacuum modes of a quantized field by a parabolic mirror is investigated. We use a geometric optics approximation to calculate the energy density and mean squared field averages for scalar and electromagnetic fields near the focus. We find that these quantities grow as an inverse power of the distance to the focus. There is an attractive Casimir-Polder force on an atom which will draw it into the focus. Some estimates of the magnitude of the effects of this focusing indicate that it may be observable.
