Unruh radiation has attracted much interest, particularly because of its relationship to Hawking radiation. But its existence has been challenged by a variety of authors, including ourselves [Phys. Lett. A 158, 31 (1991)]. The absence of a consensus may be traced to the complex challenge of dealing with the infinite number of particles of the associated heat bath. Here, we show how this problem may be obviated by using the quantum Langevin equation [Ford et al., Phys. Rev. A 37, 4419 (1988); J. Math. Phys. 6, 504 (1965)], which enables us to present a simple argument to show that, despite the existence of an Unruh temperature, there is no Unruh radiation. A key point is that the Unruh system is an equilibrium system, in contrast to the Hawking system which is a non-equilibrium system.

安鲁辐射的消亡

安鲁辐射引起了极大的兴趣，特别是因为它与霍金辐射的关系。但它的存在受到了各种作者的挑战，包括我们自己 [Phys. 莱特。A 158, 31 (1991)]。没有达成共识可以追溯到处理相关热浴中无限数量的粒子的复杂挑战。在这里，我们展示了如何通过使用量子朗之万方程 [Ford et al., Phys. Rev. A 37, 4419 (1988); J.数学。物理。6, 504 (1965)]，这使我们能够提出一个简单的论点来表明，尽管存在安鲁温度，但没有安鲁辐射。一个关键点是，安鲁系统是一个平衡系统，而霍金系统是一个非平衡系统。
