corrections of Reissner-Nordström black holes
Pablo A. Cano, Samuele Chimento, Roman Linares +2
We study the first-order in corrections to non-extremal 4-dimensional dyonic Reissner-Nordström (RN) black holes with equal electric and magnetic charges in the context of Het…
On the supersymmetric solutions of the Heterotic Superstring effective action
Andrea Fontanella, Tomas Ortin
We consider the effective action of the Heterotic Superstring to first order in alpha prime and derive the necessary and sufficient conditions that a field configuration has to sat…
On the extremality bound of stringy black holes
Pablo A. Cano, Tomas Ortin, Pedro F. Ramirez
A mild version of the weak gravity conjecture (WGC) states that extremal black holes have charge-to-mass ratio larger or equal than one when higher-curvature interactions are taken…
Lie Algebra Expansions and Actions for Non-Relativistic Gravity
Eric Bergshoeff, Jose Manuel Izquierdo, Tomas Ortin +1
We show that the general method of Lie algebra expansions can be applied to re-construct several algebras and related actions for non-relativistic gravity that have occurred in the…
