We study the entanglement entropy of a one-parameter family of exactly solvable gravities in
the two-dimensional asymptotically flat space. The islands and Page curves of eternal …

We study the Page curve and the information paradox for the Bañados-Teiteboim-Zanelli
black hole coupled to two thermal baths by applying the island paradigm. We prove that as …

The Fabbri–Russo model is a generalized model of a two-dimensional dilaton gravity theory
with various parameters “n” describing various specific gravities. Particularly, the Russo …

In this paper, we have analyzed the information paradox and its resolution using the island
proposal in Schwarzschild de-Sitter black hole spacetime. First, we study the information …

A bstract Defect extremal surface (DES) is defined by minimizing the Ryu-Takayanagi
surface corrected by the quantum theory localized on the defect, which is useful when the …

A bstract We study 4-dimensional Schwarzschild de Sitter black holes in the regime where
the black hole mass is small compared with the de Sitter scale. Then the de Sitter …

We obtain the holographic entanglement negativity for bipartite mixed states at a finite
temperature in baths described by conformal field theories dual to configurations involving …

The newly proposed island formula for entanglement entropy of Hawking radiation is
applied to spherically symmetric 4-dimensional eternal Kaluza–Klein (KK) black holes. The …

The island paradigm for the fine-grained entropy of Hawking radiation is applied to eternal
charged accelerating black holes. In the absence of the island, the entanglement entropy …

We propose a doubly holographic version of the semiclassical island formula for the
entanglement negativity in the framework of the defect AdS/BCFT correspondence where …
