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…
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…
On the generalized Komar charge of supersymmetric solutions
Tomás Ortín
We consider the supersymmetric solutions of several supergravity theories (ungauged and supergravities coupled to vector supermultiplets and…
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…
