Hidden Conformal Symmetry of the Discrete Series Scalars in dS
Kara Farnsworth, Kurt Hinterbichler, Samanta Saha
In dimensional de Sitter space, a scalar field has an infinite tower of special tachyonic mass values at which enhanced shift symmetries appear. After modding out by these shif…
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…
Scale and Conformal Invariance on (A)dS
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
We examine the question of scale versus conformal invariance on maximally symmetric curved backgrounds and study general 2-derivative conformally invariant free theories of vectors…
Dualities Among Massive, Partially Massless and Shift Symmetric Fields on (A)dS
Kurt Hinterbichler
We catalog all the electromagnetic-like dualities that exist between free dynamical bosonic fields of arbitrary symmetry type and mass on (anti-) de Sitter space in all dimensions,…
