Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

In this review, recent progress on the black hole information problem that involves a new
understanding of how to calculate the entropy of Hawking radiation is described. The review …

Abstract The Einstein Telescope (ET), a proposed European ground-based gravitational-
wave detector of third-generation, is an evolution of second-generation detectors such as …

A bstract Recent work has shown how to obtain the Page curve of an evaporating black hole
from holographic computations of entanglement entropy. We show how these computations …

A bstract Bulk quantum fields are often said to contribute to the generalized entropy\(\frac
{A}{4 {G} _N}+{S} _ {\mathrm {bulk}}\) only at O (1). Nonetheless, in the context of …

A bstract When absorbing boundary conditions are used to evaporate a black hole in
AdS/CFT, we show that there is a phase transition in the location of the quantum Ryu …

Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

A bstract In the 1980's, work by Coleman and by Giddings and Strominger linked the physics
of spacetime wormholes to 'baby universes' and an ensemble of theories. We revisit such …

A bstract Quantum error correction has given us a natural language for the emergence of
spacetime, but the black hole interior poses a challenge for this framework: at late times the …

We review recent progress and future prospects for harnessing powerful tools from
theoretical high-energy physics, such as scattering amplitudes and effective field theory, to …
