The stringy geometry of integral cohomology in mirror symmetry
Peng Cheng, Ilarion V. Melnikov, Ruben Minasian
We examine the physical significance of torsion co-cycles in the cohomology of a projective Calabi-Yau three-fold for the (2,2) superconformal field theory (SCFT) associated to the…

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…

Topology change and heterotic flux vacua
Dan Israel, Ilarion V. Melnikov, Ruben Minasian +1
We investigate the interrelation between topology and Narain T-duality of heterotic flux vacua. We present evidence that all 5 and 4-dimensional Minkowski space heterotic flux back…
