Special Issue on
Swampland and String Theory Landscape

Call for Papers

String theory provides a framework for quantising gravity and unifying it with the other fundamental interactions. A major chal- lenge is to identify our universe among a huge amount of ground states forming the string landscape. In a bottom-up approach, the swampland program consists of defining a set of criteria for low energy effective field theories that have a consistent ultraviolet completion within string theory (or within quantum gravity in general); therefore, those that do not satisfy these criteria belong to the swampland and not to the string landscape. This issue presents the progress made over the recent years on understanding the structure of the string landscape and on providing a complete set of swampland criteria and their consequences.

Topics may include but are not limited to:

General overview swampland
Weak gravity conjecture (WGC)
Swampland refined versions
SUSY breaking
String theory landscape
Distance conjecture
Constraints on QFT from probe defects/branes
The dS conjecture
KKLT
Other forms of WGC: scalars
Other forms of WGC: axions
Trans-Planckian censorship conjecture
