Non-geometric Calabi-Yau Backgrounds in String Theory

If you have a question about this talk, please contact Dr. Carl Turner .

String theory duality symmetries can be used to glue together different patches of a solution to construct what have been called ‘non-geometric spaces’; these can be good solutions of string theory even though they would not be allowed in supergravity. In this talk, some recent work with Israel and Sarti will be described that constructs non-geometric analogues of Calabi-Yau manifolds in which patches are glued together with mirror symmetry transformations to construct a ‘mirrorfold’. These solutions preserve the same amount of supersymmetry as Calabi-Yau spaces, but typically have far fewer light moduli and so lead to models with far fewer light particles.
