低温低频黑体辐射的修正
Modification of black-body radiance at low temperatures and frequencies
摘要：
与以前的报道不同，在讨论由SU（2）效应修改的光子黑体辐射的{ \sl能量密度}的光谱的地方，我们讨论了在5和20开尔文之间的温度范围内的{ \sl辐射率}的频谱。我们的结论是，与传统理论相比，唯一可观察到的效果是与光谱间隙（总屏蔽）。我们还讨论了如何在足够强的静态电场的影响下的低温黑体腔被迫发射根据普朗克辐射定律（纯U（1）理论），即使在低频率，以及如何利用这种效果来测量SU（2）诱导的偏差。
英文摘要：
In contrast to earlier reports, where the spectrum of the {\sl energy density} of photonic black-body radiation modified by SU(2) effects was discussed, we discuss the low-frequency spectrum of the {\sl radiance} at temperatures ranging between 5 and 20 Kelvin. We conclude that compared to the conventional theory the only observable effect is associated with the spectral gap (total screening). We also discuss how a low-temperature black body cavity under the influence of a sufficiently strong static electric field is forced to emit according to Planck's radiation law (pure U(1) theory) even at low frequencies and how this effect can be utilized to measure SU(2) induced deviations.
