On the generalized Komar charge of Kaluza-Klein theories and higher-form symmetries
G. Barbagallo, J. L. V. Cerdeira, C. Gómez-Fayrén +2
The generalized Komar -form charge can be modified by the addition of any other on-shell closed (conserved) -form charge. We show that, with Kaluza--Klein boundary co…
A note on the calculation of the Komar integral in the Lorentzian Taub-NUT spacetime
Gabriele Barbagallo, José Luis V. Cerdeira, Carmen Gómez-Fayrén +1
It has recently been shown that one can derive consistent thermodynamical expressions in the Lorentzian Taub--NUT spacetime keeping the Misner-string singularities and taking into…
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…
Democratic actions with scalar fields: symmetric sigma models, supergravity actions and the effective theory of the type IIB superstring
Jose Juan Fernandez-Melgarejo, Giacomo Giorgi, Carmen Gomez-Fayren +2
The dualization of the scalar fields of a theory into (d-2)-form potentials preserving all the global symmetries is one of the main problems in the construction of democratic pseud…
Covariant generalized conserved charges of General Relativity
Carmen Gómez-Fayrén, Patrick Meessen, Tomás Ortín
Motivated by the current research of generalized symmetries and the construction of conserved charges in pure Einstein gravity linearized over Minkowski spacetime in Cartesian coor…
Wald entropy in Kaluza-Klein black holes
Carmen Gomez-Fayren, Patrick Meessen, Tomas Ortin +1
We study the thermodynamics of the 4-dimensional electrically charged black-hole solutions of the simplest 5-dimensional Kaluza-Klein theory using Wald's formalism. We show how the…
