Shift orbifolds, decompactification limits, and lattices
arXiv:2502.18453 · doi:10.21468/SciPostPhys.20.2.039
Abstract
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 theories and describe some applications to the CFT based on the Leech lattice and its shift orbifolds.
