The Komar charges of type II supergravity and supersymmetric localization
Gabriele Barbagallo, G. Barbagallo, Tomás Ortín +1
We compute the on-shell closed, generalized Komar charges associated to an arbitrary Killing vector of the two 10-dimensional supergravity theories which are the lo…
Gravity-Informed Neural Networks for Post-Newtonian Binary Dynamics
Gabriele Barbagallo, Javier Matulich
We introduce a gravity-informed neural-network (GravINNs) framework for learning post-Newtonian binary orbital dynamics. The method incorporates the equations of motion directly in…
Derivation of the Smarr formula from the Komar charge in Einstein-nonlinear electrodynamics theories and applications to regular black holes
Gabriele Barbagallo, Tomás Ortín
We construct the generalized Komar charge of generic, non-linear theories of electrodynamics (NLED) in 4 dimensions coupled to Einstein gravity. The contribution of the dimensionfu…
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…
