Entanglement entropy plays a variety of roles in quantum field theory, including the
connections between quantum states and gravitation through the holographic principle. This …

A remarkable yet mysterious property of black holes is that their entropy is proportional to the
horizon area. This area law inspired the holographic principle, which was later realized …

A bstract We use the Einstein-Hilbert gravitational path integral to investigate gravita-tional
entanglement at leading order O (1/G). We argue that semiclassical states prepared by a …

We study the contribution to the entanglement entropy of (2+ 1)-dimensional conformal field
theories (CFTs) coming from a sharp corner in the entangling surface. This contribution is …

This short review is intended as a colloquium-level summary, for the Snowmass 2021
process, on recent theoretical results on infrared observables in quantum gravity. We rely on …

A bstract We construct a new class of entanglement measures by extending the usual
definition of Rényi entropy to include a chemical potential. These charged Rényi entropies …

A bstract We study the spectrum of local operators living on a defect in a generic conformal
field theory, and their coupling to the local bulk operators. We establish the existence of …

Motivated by recent work suggesting observably large spacetime fluctuations in the causal
development of an empty region of flat space, we conjecture that these metric fluctuations …

A bstract We propose a field theoretic framework for calculating the dependence of Rényi
entropies on the shape of the entangling surface in a conformal field theory. Our approach …

We study entanglement entropy (EE) in conformal field theories (CFTs) in Minkowski space
with a planar boundary or with a planar defect of any codimension. In any such boundary …
