We review constructions of three-dimensional 'quantum'black holes. Such spacetimes arise
via holographic braneworlds and are exact solutions to an induced higher-derivative theory …

A bstract We develop a new setting in the framework of braneworld holography to describe a
pair of coupled and entangled uniformly accelerated universes. The model consists of two …

In this Letter, we show that Jackiw-Teitelboim gravity can be naturally realized in the Karch-
Randall braneworld. Notably the role of the dilaton in Jackiw-Teitelboim gravity is played by …

A bstract Entanglement islands play an essential role in the recent breakthrough in resolving
the black hole information paradox. However, whether entanglement islands can exist in …

A bstract It is controversial whether entanglement islands can exist in massless gravity
theories. Recently, it is found that the massless entanglement island appears in wedge …

A bstract Double holography offers a profound understanding of the island formula by
describing a gravitational system on AdS d coupled to a conformal field theory on ℝ 1, d− 1 …

A bstract In this paper, we study the dynamics of end-of-the-world (EOW) branes in AdS with
scalar fields localized on the branes as a new class of gravity duals of CFTs on manifolds …

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 The previous studies of the island and double holography mainly focus on
codimension-one branes. This paper explores the island on the codimension-two brane in …

A bstract We study black holes in two and three dimensions that have spacelike curvature
singularities behind horizons. The 2D solutions are obtained by dimensionally reducing …
