Description

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 construct type II T^6/Z_9 islands with 16 supercharges, study the structure of their supersymmetry multiplets and compute helicity supertraces to prove the existence of an archipelago.
