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…
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…
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-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…
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…
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…
