The swampland: introduction and review

E Palti - Fortschritte der Physik, 2019‏ - Wiley Online Library
The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

Jerusalem lectures on black holes and quantum information

D Harlow - Reviews of Modern Physics, 2016‏ - APS
These lectures give an introduction to the quantum physics of black holes, including recent
developments based on quantum information theory such as the firewall paradox and its …

Distance and de Sitter Conjectures on the Swampland

H Ooguri, E Palti, G Shiu, C Vafa - Physics Letters B, 2019‏ - Elsevier
Among Swampland conditions, the distance conjecture characterizes the geometry of scalar
fields and the de Sitter conjecture constrains allowed potentials on it. We point out a …

Holographic complexity equals bulk action?

AR Brown, DA Roberts, L Susskind, B Swingle, Y Zhao - Physical review letters, 2016‏ - APS
We conjecture that the quantum complexity of a holographic state is dual to the action of a
certain spacetime region that we call a Wheeler-DeWitt patch. We illustrate and test the …

Complexity, action, and black holes

AR Brown, DA Roberts, L Susskind, B Swingle, Y Zhao - Physical Review D, 2016‏ - APS
Our earlier paper “Complexity Equals Action” conjectured that the quantum computational
complexity of a holographic state is given by the classical action of a region in the bulk (the …

Generalized black hole entropy is von Neumann entropy

J Kudler-Flam, S Leutheusser, G Satishchandran - Physical Review D, 2025‏ - APS
It has been argued that, while the individual terms in the generalized entropy, S gen= A/4
GN+ S ext, are ill-defined in the semiclassical limit, their sum is well-defined if one takes into …

Quantum focusing conjecture

R Bousso, Z Fisher, S Leichenauer, AC Wall - Physical Review D, 2016‏ - APS
We propose a universal inequality that unifies the Bousso bound with the classical focusing
theorem. Given a surface σ that need not lie on a horizon, we define a finite generalized …

Entanglement equilibrium and the Einstein equation

T Jacobson - Physical review letters, 2016‏ - APS
A link between the semiclassical Einstein equation and a maximal vacuum entanglement
hypothesis is established. The hypothesis asserts that entanglement entropy in small …

Thermodynamical aspects of gravity: new insights

T Padmanabhan - Reports on Progress in Physics, 2010‏ - iopscience.iop.org
The fact that one can associate thermodynamic properties with horizons brings together
principles of quantum theory, gravitation and thermodynamics and possibly offers a window …

The Unruh effect and its applications

LCB Crispino, A Higuchi, GEA Matsas - Reviews of Modern Physics, 2008‏ - APS
It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in
our understanding that the particle content of a field theory is observer dependent. This …
