Shift Symmetries in (Anti) de Sitter Space
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon sy…
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…
