Lectures on the swampland program in string compactifications
M van Beest, J Calderón-Infante, D Mirfendereski… - Physics Reports, 2022 - Elsevier
The Swampland program aims to determine the constraints that an effective field theory must

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 …

de Sitter Space and the Swampland
It has been notoriously difficult to construct a meta-stable de Sitter (dS) vacuum in string
theory in a controlled approximation. This suggests the possibility that meta-stable dS …

Bounds on slow roll and the de Sitter swampland
SK Garg, C Krishnan - Journal of High Energy Physics, 2019 - Springer
The recently introduced swampland criterion for de Sitter [17] can be viewed as a
(hierarchically large) bound on the smallness of the slow roll parameter 𝜖 V. This leads us to …

Cosmological backgrounds of gravitational waves
C Caprini, DG Figueroa - Classical and Quantum Gravity, 2018 - iopscience.iop.org
Gravitational waves (GWs) have a great potential to probe cosmology. We review early
universe sources that can lead to cosmological backgrounds of GWs. We begin by …

Review of the no-boundary wave function
JL Lehners - Physics Reports, 2023 - Elsevier
When the universe is treated as a quantum system, it is described by a wave function. This
wave function is a function not only of the matter fields, but also of spacetime. The no …

The string landscape, the swampland, and the missing corner
We give a brief overview of the string landscape and techniques used to construct string
compactifications. We then explain how this motivates the notion of the swampland and …
