Residual gauge symmetry in light-cone electromagnetism
Sucheta Majumdar
We analyze the residual gauge freedom in light-cone electromagnetism in four dimensions. The standard boundary conditions involved in the so-called formalism, which contains…
Kaluza-Klein Spectrometry beyond Consistent Truncations: The Squashed
Bastien Duboeuf, Emanuel Malek, Henning Samtleben
We show how to use Exceptional Field Theory to compute the full Kaluza-Klein spectra of 10- and 11-dimensional supergravity around deformations of backgrounds of maximal gauged sup…
U-duality and corrections in three dimensions
Camille Eloy, Olaf Hohm, Henning Samtleben
We consider the target space theory of bosonic and heterotic string theory to first order in compactified to three dimensions, using a formulation that is manifestly T-duality…
Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
Marc Geiller, Florian Girelli, Christophe Goeller +1
We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary…
3D Quantum Gravity from Holomorphic Blocks
Etera R. Livine, Qiaoyin Pan
Three-dimensional gravity is a topological field theory, which can be quantized as the Ponzano-Regge state-sum model built from the -symbols of the recoupling of the $\SU(…
Supersymmetric action for 6D supergravity
Yannick Bertrand, Stefan Hohenegger, Olaf Hohm +1
We give a linearized but otherwise complete supersymmetric action for supergravity in six dimensions, using a Kaluza-Klein-type split of coordinates and fiel…
