Shift orbifolds, decompactification limits, and lattices
Dan Israel, Ilarion V. Melnikov, Yann Proto
We describe the general shift orbifold of a Narain CFT and use this to investigate decompactification limits in the heterotic Narain moduli space. We also comment on higher rank th…
Heterotic/type II Duality and Non-Geometric Compactifications
Yoan Gautier, Chris M. Hull, Dan Israël
We present a new class of dualities relating non-geometric Calabi-Yau compactifications of type II string theory to T-fold compactifications of the heterotic string, both preservin…
Non-geometric Calabi-Yau Backgrounds and K3 automorphisms
Chris Hull, Dan Israel, Alessandra Sarti
We 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…
Non-geometric Calabi-Yau compactifications and fractional mirror symmetry
Dan Israel
We construct a wide class of non-geometric compactifications of type II superstring theories preserving N=1 space-time supersymmetry in four dimensions, starting from Calabi-Yau co…
Fractional Mirror Symmetry
Dan Israel
Mirror symmetry relates type IIB string theory on a Calabi-Yau 3-fold to type IIA on the mirror CY manifold, whose complex structure and Kaehler moduli spaces are exchanged. We sho…
Local models of heterotic flux vacua: spacetime and worldsheet aspects
Luca Carlevaro, Dan Israel
We report on some recent progress in understanding heterotic flux compactifications, from a worldsheet perspective mainly. We consider local models consisting in torus fibration ov…
