标题： Dynamical collapse for photons

摘要： 我建议对我的连续自发定位（CSL）理论做一简单的修正，用相对论性的能量密度算符代替质量密度塌缩生成算符。 探讨了密度矩阵演化方程的一些后果。 首先，计算了自由粒子平均动能增加的表达式（在非相对论极限下，与通常的结果一致）。 然后，将密度矩阵演化应用于光子。 以塌缩率参数 $\lambda$ 的一级近似处理了激光束脉冲中光子数损失的平均速率、“激发”出激光束脉冲的光子动量分布以及宇宙黑体谱的变化。 讨论了与 $\lambda$ 相关的可能实验限制。 显示英文摘要

摘要： I suggest a simple alteration of my CSL (Continuous Spontaneous Localization) theory, replacing the mass density collapse-generating operators by relativistic energy density operators. Some consequences of the density matrix evolution equation are explored. First, the expression for the mean energy increase of free particles is calculated (which, in the non-relativistic limit, agrees with the usual result). Then, the density matrix evolution is applied to photons. The mean rate of loss of photon number from a laser beam pulse, the momentum distribution of the photons "excited" out of the laser beam pulse, and the alteration of the cosmic blackbody spectrum are all treated to first order in the collapse rate parameter $\lambda$. Associated possible experimental limits on $\lambda$ are discussed.
