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…
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…
M5 branes on ADE singularities: BPS spectrum and partition functions
Daniele Ceppi, Guglielmo Lockhart
The dynamics of a stack of M5 branes probing a transverse multi-centered Taub-NUT space are described by a class of 6d superconformal field theories known as th…
The hyperplane string, RCFTs, and the swampland
Guglielmo Lockhart, Luca Novelli
Six dimensional supergravity features BPS strings whose properties encode highly nontrivial information about the parent 6d theory. We focus on a distinguished…
Modular Exercises for Four-Point Blocks -- I
Miranda C. N. Cheng, Terry Gannon, Guglielmo Lockhart
The well-known modular property of the torus characters and torus partition functions of (rational) vertex operator algebras (VOAs) and 2d conformal field theories (CFTs) has been…
