CSL模型中原子系统的光子发射率

Photon emission rate from atomic systems in the CSL model

Stephen L. Adler, Fethi M. Ramazanoglu

摘要:

在质量成比例的CSL模型下计算了一般原子系统的光子发射率.对于发射千伏γ射线的孤立带电粒子,我们的结果与Fu的结果一致。对于中性原子系统,光子发射强烈抑制光子波长远大于原子半径。然而,对于千伏伽马射线,Fu的结果被一个结构因子修正,该结构因子具有统一的阶数,没有速率抑制。我们的计算很容易推广到非白噪声的情况下,噪声耦合,不是质量成比例的,和一般(非高斯)空间关联函数,并给出相应的结果。我们简要地讨论了我们的CSL模型参数的上限计算的影响。

英文摘要:

We calculate the photon emission rate from a general atomic system in the mass- proportional CSL model. For an isolated charged particle emitting kilovolt gamma rays, our results agree with those obtained by Fu. For a neutral atomic system, photon emission is strongly suppressed for photon wavelengths much larger than the atomic radius. However, for kilovolt gamma rays, Fu's result is modified by a structure factor that is of order unity, giving no rate suppression. Our calculation is readily generalized to the case of non-white noise, noise couplings that are not mass-proportional, and general (non-Gaussian) spatial correlation functions, and corresponding results are given. We briefly discuss the implications of our calculation for upper bounds on the CSL model parameters.
