We show that there is a classical metric satisfying the Einstein equations outside a finite
spacetime region where matter collapses into a black hole and then emerges from a white …

We calculate the time evolution of entanglement entropy in two-dimensional conformal field
theory with a moving mirror. For a setup modeling Hawking radiation, we obtain a linear …

Moving mirrors have been known as tractable setups modeling Hawking radiation from
black holes. In this paper, motivated by recent developments regarding the black hole …

A bstract We consider the capacity of entanglement in models related with the gravitational
phase transitions. The capacity is labeled by the replica parameter which plays a similar role …

This study focuses on the examination of the island rule within the context of four-
dimensional Reissner-Nordström-anti-de Sitter (4D RN-AdS) black holes, illuminating the …

A bstract In this work, we demonstrate that quantizing gravity on a null hypersurface leads to
the emergence of a CFT associated with each null ray. This result stems from the ultralocal …

A bstract We study the effects of horizons on the entanglement harvested between two
Unruh-DeWitt detectors via the use of moving mirrors with and without strict horizons. The …

A bstract We systematically study moving mirror models in two-dimensional conformal field
theory (CFT). By focusing on their late-time behavior, we separate the mirror profiles into four …

In a quantum system in a pure state, a subsystem generally has a nonzero entropy because
of entanglement with the rest of the system. Is the average entanglement entropy of pure …

The dust ball collapse is studied in the context of the “rainbow metric” approach (where the
matter content is supplemented with a scalar field perturbation) to the Oppenheimer-Snyder …
