霍金效应导致的黑洞蒸发过程与量子力学幺正演化的潜在冲突引起了激烈的争论。最近，我们中的一个人合作完成了一系列工作，修正了这场争论，目的是一方面澄清围绕它的一些概念问题，同时论证坍缩理论有可能为所谓的悖论提供令人满意的解决方案。在这里，我们使用一个简化的黑洞产生和蒸发模型（称为CGHS模型），结合一个动力学约化理论（称为CSL），以及一些关于量子引力与可能的奇点有关的作用的推测性但似乎是自然的想法，显示了一个支持这一说法的明确计算。这项工作代表了Okon和Sudarsky（Found Phys 44：114-143，2014）首次讨论的一般思想的具体实现，以及Modak等人（Phys Rev D 91（12）：124009，2015）首次考虑的模型的完整和详细分析。
The process of black hole evaporation resulting from the Hawking effect has generated an intense controversy regarding its potential conflict with quantum mechanics’ unitary evolution. A recent set of works by a collaboration involving one of us, have revised the controversy with the aims of, on one hand, clarifying some conceptual issues surrounding it, and, at the same time, arguing that collapse theories have the potential to offer a satisfactory resolution of the so-called paradox. Here we show an explicit calculation supporting this claim using a simplified model of black hole creation and evaporation, known as the CGHS model, together with a dynamical reduction theory, known as CSL, and some speculative, but seemingly natural ideas about the role of quantum gravity in connection with the would-be singularity. This work represents a specific realization of general ideas first discussed in Okon and Sudarsky (Found Phys 44:114–143, 2014) and a complete and detailed analysis of a model first considered in Modak et al. (Phys Rev D 91(12):124009, 2015).
