论文摘要
杂种量子状态是用于物理颗粒的hartle-hawking状态的组合，而不是物理粒子（例如幽灵）的boulware态，这是我们较早的工作中引入的[1]。我们基于第一个模型提供了一个二维示例，当相应的背部空间是一种因果钻石，地球上完整并且没有曲率奇异性。在静态情况下，它在模仿黑洞的虫洞结构中没有显示地平线的存在。在动态情况下，由于经典物质的脉搏而扰动，显而易见的是horion，而时空仍然是常规的因果钻石。我们在静态和动态情况下计算渐近辐射。我们定义了渐近辐射的熵，并证明，作为智障时间的函数，它显示了页面曲线的典型行为。我们建议用在时空中自发产生的物理和非物理粒子的虚拟对中的相关性来解释我们的发现。
A hybrid quantum state is a combination of the Hartle-Hawking state for the physical particles and the Boulware state for the non-physical ones (such as ghosts), as was introduced in our earlier work [1]. We present a two-dimensional example, based on the RST model, when the corresponding back-reacted spacetime is a causal diamond, geodesically complete and free of the curvature singularities. In the static case it shows no presence of the horizon while it has a wormhole structure mimicking the black hole. In the dynamical case, perturbed by a pulse of classical matter, there appears an apparent horion while the spacetime remains to be a regular causal diamond. We compute the asymptotic radiation both in the static and dynamic case. We define entropy of the asymptotic radiation and demonstrate that as a function of the retarded time it shows the behavior typical for the Page curve. We suggest interpretation of our findings in terms of correlations in the virtual pairs of physical and non-physical particles spontaneously created in the spacetime.
