A Partially Massless Superconductor
Kurt Hinterbichler, Austin Joyce
We describe a Higgs mechanism for the partially massless graviton. In order to do so, we first construct a covariant fracton-like effective field theory on de Sitter space that lin…
Impossible Symmetries and Conformal Gravity
Kurt Hinterbichler, Austin Joyce, Grégoire Mathys
We explore the physics of relativistic gapless phases defined by a mixed anomaly between two generalized conserved currents. The gapless modes can be understood as Goldstone modes…
The graviton four-point function in de Sitter space
James Bonifacio, Harry Goodhew, Austin Joyce +2
We compute the tree-level late-time graviton four-point correlation function, and the related quartic wavefunction coefficient, for Einstein gravity in de Sitter spacetime. We deri…
Soft theorems for boosts and other time symmetries
Lam Hui, Austin Joyce, Ilia Komissarov +3
We derive soft theorems for theories in which time symmetries -- symmetries that involve the transformation of time, an example of which are Lorentz boosts -- are spontaneously bro…
Exploring Answers to Questions
Jonathan J. Heckman, Austin Joyce, Jeremy Sakstein +1
We explore potential uses of physics formulated in Kleinian (i.e., ) signature spacetimes as a tool for understanding properties of physics in Lorentzian (i.e., ) signatu…
Gravity as a gapless phase and biform symmetries
Kurt Hinterbichler, Diego M. Hofman, Austin Joyce +1
We study effective field theories (EFTs) enjoying (maximal) biform symmetries. These are defined by the presence of a conserved (electric) current that has the symmetries of a Youn…
