String probes, simple currents, and the no global symmetries conjecture
Guglielmo Lockhart, Luca Novelli, Yann Proto
Center one-form symmetries in consistent quantum gravity theories are expected to be either broken or gauged, thereby determining the global form of the gauge group. We shed light…
Rational points in the 6d supergravity landscape and simple current extensions
Guglielmo Lockhart, Yann Proto
We investigate a recently identified class of six-dimensional supergravities without tensor multiplets whose primitive BPS strings are described by a rational superconformal field…
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…
