@article{Hull2017NongeometricCB, title={Non-geometric Calabi-Yau backgrounds and K3 automorphisms}, author={Christopher M. Hull and Dan Isra{\"e}l and Alessandra Sarti}, journal={Journal of High Energy Physics}, year={2017}, volume={2017}, pages={1-44} }

A bstractWe consider compactifications of type IIA superstring theory on mirror-folds obtained as K3 fibrations over two-tori with non-geometric monodromies involving mirror symmetries. At special points in the moduli space these are asymmetric Gepner models. The compactifications are constructed from non-geometric automorphisms that arise from the diagonal action of an automorphism of the K3 surface and of an automorphism of the mirror surface. We identify the corresponding gaugings of N…
