Gravitational currents and charges from conformal Killing-Yano tensors
Chris Hull, Ulf Lindström, Maxwell L. Velásquez Cotini Hutt
We construct a set of higher-form conserved currents on spacetimes admitting conformal Killing-Yano tensors. We find relations between these currents that allow the charge given by…
Gauge-invariant charges of the dual graviton
Chris Hull, Ulf Lindström, Maxwell L. Velásquez Cotini Hutt
The free graviton theory given by linearising Einstein's theory has a dual formulation in terms of a dual graviton field. The dual graviton theory has two gauge invariances giving…
Generalised symmetries in linear gravity
Chris Hull, Maxwell L Hutt, Ulf Lindström
Linearised gravity has a global symmetry under which the graviton is shifted by a symmetric tensor satisfying a certain flatness condition. There is also a dual symmetry that can b…
Gauging generalised symmetries in linear gravity
Chris Hull, Maxwell L Hutt, Ulf Lindström
The theory of a free spin-2 field on Minkowski spacetime has 1-form and -form symmetries associated with conserved currents formed by contractions of the linearised Riemann…
On the maximally symmetric vacua of generic Lovelock gravities
Deniz Olgu DevecioÄlu, Ulf Lindström, Ãzgür SarıoÄlu
We survey elementary features of Lovelock gravity and its maximally symmetric vacuum solutions. The latter is solely determined by the real roots of a dimension-dependent polynomia…
