我们讨论的电磁性质的带电自由粒子，和一个带电粒子的谐波势的约束下，崩溃模型。通过选择一个特别简单但与物理相关的坍缩模型，并且仅在偶极近似下，我们能够精确地求解运动方程。这样，有限时间和大时间行为都可以被准确地分析。我们发现了新的特征，这在以前的同一主题的作品中没有出现。由于，到目前为止，自发光子发射过程中的崩溃参数的最强上限，我们的研究结果要求进一步分析这个过程中的原子系统，可用于实验测试的崩溃模型，以及量子力学。
We discuss the electromagnetic properties of both a charged free particle, and a charged particle bounded by an harmonic potential, within collapse models. By choosing a particularly simple-yet physically relevant-collapse model, and under only the dipole approximation, we are able to solve the equation of motion exactly. In this way, both the finite-time and large-time behavior can be analyzed accurately. We discovered new features, which did not appear in previous works on the same subject. Since, so far, the spontaneous photon emission process places the strongest upper bounds on the collapse parameters, our results call for a further analysis of this process for those atomic systems which can be employed in experimental tests of collapse models, as well as of quantum mechanics.
