A bstract We study the information paradox for the eternal black hole with charges on a
doubly-holographic model in general dimensions, where the charged black hole on a …

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 We study the entanglement entropy for time-like subsystem in two-dimensional
boundary conformal field theory (BCFT) both from the field theory and holographic point of …

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 In this paper, we investigate AdS/BCFT for curvature-squared gravity. To warm up,
we start with Gauss-Bonnet gravity. We derive the one point function of stress tensor and …

A bstract Recently, a codimension two holography called wedge holography is proposed as
a generalization of AdS/CFT. It is conjectured that a gravitational theory in d+ 1 dimensional …

A bstract We propose defect extremal surface as the holographic counterpart of boundary
quantum extremal surface. The defect extremal surface is defined by minimizing the Ryu …

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 Motivated by questions about quantum information and classification of quantum
field theories, we consider Conformal Field Theories (CFTs) in spacetime dimension d≥ 5 …

We investigate the entanglement between the eternal black hole and Hawking radiation. For
this purpose, we utilize the doubly holographic theories and study the entanglement entropy …
