56. Supersymmetric AdS Solitons, Coulomb Branch Flows, Twisted Compactifications and their Marginal Deformations

Madi Hammond (Swansea University)

17/12/2025, 17:00

I will speak about the papers https://arxiv.org/pdf/2506.10062v3 and another two to appear shortly.

We construct and analyse infinite classes of regular supergravity backgrounds dual to four-dimensional SCFTs compactified on a circle
with a supersymmetry-preserving twist. These flows lead to three-dimensional gapped QFTs preserving four supercharges. The solutions arise in Type IIB, Type...

57. 4-dimensional string islands from asymmetric orbifolds

Elisa Iris Marieni (University of Southampton)

String islands are isolated points in the space of worldsheet conformal field theories that have reduced number of moduli, enjoy rank reduction and lead to consistent pure supergravity theories. Asymmetric orbifold constructions are powerful tools that enable us to access these points in the moduli space that are inaccessible to more standard string compactification techniques. In this talk, I...
