corrections to 4-dimensional non-extremal stringy black holes
Matteo Zatti
We compute the first-order corrections to a family of 4-dimensional, 4-charge, non-extremal black hole solutions of Heterotic Supergravity in the case with 3 independent charg…
Torsion in cohomology and dimensional reduction
Gonzalo F. Casas, Fernando Marchesano, Matteo Zatti
Conventional wisdom dictates that factors in the integral cohomology group of a compact manifold cannot be computed via smooth -forms…
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…
On scalar charges and black-hole thermodynamics
Romina Ballesteros, Carmen Gómez-Fayrén, Tomás Ortín +1
We revisit the first law of black hole thermodynamics in 4-dimensional theories containing scalar and Abelian vector fields coupled to gravity using Wald's formalism and a new defi…
New instabilities for non-supersymmetric AdS orientifold vacua
Fernando Marchesano, Joan Quirant, Matteo Zatti
We consider massive type IIA orientifold compactifications of the form AdS, where admits a Calabi-Yau metric and is threaded by background fluxes. From a 4d vi…
Non-supersymmetric black holes with corrections
Pablo A. Cano, Tomás Ortín, Alejandro Ruipérez +1
We study extremal 5- and 4-dimensional black hole solutions of the Heterotic Superstring effective action at first order in with, respectively, 3 and 4 charges of arbitrary si…
