摘要
A hybrid quantum state is a combination of the Hartle-Hawking state for thephysical particles and the Boulware state for the non-physical ones (such asghosts), as was introduced in our earlier work [1]. We present atwo-dimensional example, based on the RST model, when the correspondingback-reacted spacetime is a causal diamond, geodesically complete and free ofthe curvature singularities. In the static case it shows no presence of thehorizon while it has a wormhole structure mimicking the black hole. In thedynamical case, perturbed by a pulse of classical matter, there appears anapparent horion while the spacetime remains to be a regular causal diamond. Wecompute the asymptotic radiation both in the static and dynamic case. We defineentropy of the asymptotic radiation and demonstrate that as a function of theretarded time it shows the behavior typical for the Page curve. We suggestinterpretation of our findings in terms of correlations in the virtual pairs ofphysical and non-physical particles spontaneously created in the spacetime.
