Description
String islands are isolated points in the space of string vacua that have no moduli except the dilaton, 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, we classify all supersymmetry-breaking crystallographic SO(6) elements and use them to populate the landscape of type II vacua. To construct heterotic vacua, we take as orbifold actions automorphisms of the Leech lattice. In this landscape of 4d N=4 theories we identify many island candidates, explicitly construct some of them and show the appearance of archipelagos.
