In this review article, we discuss the distinction and possible equivalence between scale
invariance and conformal invariance in relativistic quantum field theories. Under some …

The entanglement entropy has been historically studied by many authors in order to obtain
quantum mechanical interpretations of the gravitational entropy. The discovery of anti-de …

Late-time dominance of entanglement islands plays a critical role in addressing the
information paradox for black holes in AdS coupled to an asymptotic non-gravitational bath …

A bstract We discuss holographic models of extremal and non-extremal black holes in
contact with a bath in d dimensions, based on a brane world model introduced in [1]. The …

A bstract Recent progress in our understanding of the black hole information paradox has
lead to a new prescription for calculating entanglement entropies, which involves special …

We consider two dimensional CFT states that are produced by a gravitational path integral.
As a first case, we consider a state produced by Euclidean AdS2 evolution followed by flat …

It has been suggested in recent work that the Page curve of Hawking radiation can be
recovered using computations in semi-classical gravity provided one allows for" islands" in …

We formulate a version of the information paradox in de Sitter spacetime and show that it is
solved by the emergence of entanglement islands in the context of the De Sitter/de Sitter …

A bstract In this note, following [1–3], we introduce and study various holographic systems
which can describe evaporating black holes. The systems we consider are boundary …

For the first time, a gravitational calculation was recently shown to yield the Page curve for
the entropy of Hawking radiation, consistent with unitary evolution. However, the calculation …
