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…
Monopoles, Dirac Strings and Generalised Symmetries
C M Hull
Dirac's formulation of magnetic monopoles is shown to be equivalent to Maxwell theory coupled to 2-form gauge fields so that it has a local 1-form symmetry, with the 2-form gauge f…
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…
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…
Gauge-invariant magnetic charges in linearised gravity
Chris Hull, Maxwell L. Hutt, Ulf Lindström
Linearised gravity has magnetic charges carried by (linearised) Kaluza-Klein monopoles. A gauge-invariant expression is found for these charges that is similar to Penrose's gauge-i…
superfields and geometry revisited
Chris Hull, Maxim Zabzine
We take a fresh look at the relation between generalised Kähler geometry and supersymmetric sigma models in two dimensions formulated in terms of superfields. Dua…
Charges and topology in linearised gravity
Chris Hull, Maxwell L. Hutt, Ulf Lindström
Covariant conserved 2-form currents for linearised gravity are constructed by contracting the linearised curvature with conformal Killing-Yano tensors. The corresponding conserved…
