Komar charge of N = 2 supergravity and its superspace generalization
Igor Bandos, Patrick Meessen, Tomás Ortín
We find the defining equations for a Killing vector and its superpartner (called the generalized Killing spinor) and use them to construct the generalized Komar superform of minima…
Black hole solutions in theories of supergravity
Tomás Ortín
Supergravity has played a very important role in many advances and developments in black hole physics. Here I will review the history of some of them.
On the thermodynamics of the black holes of the Cano-Ruipérez 4-dimensional string effective action
Tomás Ortín, Matteo Zatti
The Cano-Ruipérez 4-dimensional string effective action is the simplest consistent truncation of the first-order in heterotic string effective action compactified on T.…
A note on the Noether-Wald and generalized Komar charges
Tomás Ortín, Matteo Zatti
We propose a simple algorithm to compute the generalized Komar charge of any exactly gauge- and diffeomorphism-invariant theory.
Noether-Wald and Komar charges in supergravity, fermions, and Killing supervectors in superspace
Igor Bandos, Patrick Meessen, Tomás Ortín
The supersymmetry properties of Killing vectors and spinors in supergravity theory can be clarified by relating them to Killing supervectors in the supergravity superspace. In the…
Gravitational higher-form symmetries and the origin of hidden symmetries in Kaluza-Klein compactifications
Carmen Gómez-Fayrén, Tomás Ortín, Matteo Zatti
We show that, in presence of isometries and non-trivial topology, the Einstein--Hilbert action is invariant under certain transformations of the metric which are not diffeomorphism…
