Non-renormalisation of coupling constants from categorical symmetries in two dimensions
Guillermo Arias-Tamargo, Chris Hull, Maxwell L. Velásquez Cotini Hutt
We study the role of categorical symmetries in constraining the renormalisation of couplings in two-dimensional non-linear sigma models with Wess-Zumino term. A large class of thes…
The Symplectic Geometry of p-Form Gauge Fields
Chris Hull, Maxim Zabzine
We formulate interacting antisymmetric tensor gauge theory in a configuration space consisting of a pair of dual field strengths which has a natural symplectic structure. The field…
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…
Non-invertible symmetries of two-dimensional Non-Linear Sigma Models
Guillermo Arias-Tamargo, Chris Hull, Maxwell L. Velásquez Cotini Hutt
Global symmetries can be generalised to transformations generated by topological operators, including cases in which the topological operator does not have an inverse. A family of…
Coupling Self-Dual p-Form Gauge Fields to Self-Dual Branes
Chris Hull
In dimensions, -form gauge fields (with ) with self-dual field strengths couple naturally to dyonic branes with equal electric and magnetic charges. Sen's action…
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…
Magnetic Charges for the Graviton
C. M. Hull
Symmetries and conserved charges are investigated for linearised gravity and its dual formulation in terms of the dual graviton field. Conserved charges are constructed for the dua…
Covariant Action for Self-Dual p-Form Gauge Fields in General Spacetimes
C. M. Hull
Sen's action for a -form gauge field with self-dual field strength coupled to a spacetime metric involves an explicit Minkowski metric and the presence of this raises questi…
