There is strong evidence that the area of any surface limits the information content of
adjacent spacetime regions, at 1.4× 10 69 bits per square meter. This article reviews the …

We review the present status of black hole thermodynamics. Our review includes discussion
of classical black hole thermodynamics, Hawking radiation from black holes, the generalized …

An explicit model allowing a unified description of microscopic and macroscopic systems is
exhibited. First, a modified quantum dynamics for the description of macroscopic objects is …

We outline the experimental concept and key scientific capabilities of AION (Atom
Interferometer Observatory and Network), a proposed experimental programme using cold …

We study information retrieval from evaporating black holes, assuming that the internal
dynamics of a black hole is unitary and rapidly mixing, and assuming that the retriever has …

In finite entropy systems, real-time partition functions do not decay to zero at late time.
Instead, assuming random matrix universality, suitable averages exhibit a growing" ramp" …

Quantum dynamical maps provide suitable mathematical representation of quantum
evolutions. When representing quantum states by density operators, the evident …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

The wave function of an interacting 'family'of one large 'parent'and many Planck-sized
'baby'universes is computed in a semiclassical approximation using an adaptation of Hartle …

A bstract We apply the recently proposed quantum extremal surface construction to calculate
the Page curve of the eternal Reissner-Nordström black holes in four dimensions ignoring …
