Higher-form symmetries in supergravity, scalar charges and black-hole thermodynamics
Gabriele Barbagallo, José Luis V. Cerdeira, Carmen Gómez-Fayrén +2
Minimal 5-dimensional supergravity compactified on a circle gives the T model of supergravity, whose duality group is SL. We study exhaust…

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…
