Abstract In two-derivative theories of gravity coupled to matter, charged black holes are self-attractive at large distances, with the force vanishing at zero temperature. However, in the presence of massless scalar fields and four-derivative corrections, zero-temperature black holes no longer need to obey the no-force condition. In this paper, we show how to calculate the long-range force between such black holes. We develop an efficient method for computing the higher-derivative corrections…

We compute the first-order α′ corrections to well-known families of heterotic multicenter black-hole solutions in five and four dimensions. The solutions can be either supersymmetric or
Planar Black Holes as a Route to Understanding the Weak Gravity Conjecture
One version of the Weak Gravity Conjecture requires that it should be possible for an extremal black hole to emit a smaller black hole: that is, the original black hole bifurcates. For asymptotically
Four-derivative Corrections to Minimal Gauged Supergravity in Five Dimensions
: We study four-derivative corrections to pure N = 2, D = 5 gauged supergravity. In particular, we find that, up to field redefinitions, there is a single four-derivative superinvariant that one can add


The String landscape, black holes and gravity as the weakest force
We conjecture a general upper bound on the strength of gravity relative to gauge forces in quantum gravity. This implies, in particular, that in a four-dimensional theory with gravity and a U(1)
Proof of the weak gravity conjecture from black hole entropy
A bstractWe prove that higher-dimension operators contribute positively to the entropy of a thermodynamically stable black hole at fixed mass and charge. Our results apply whenever the dominant
The Weak Gravity Conjecture, RG Flows, and Supersymmetry.
We study one-loop divergences in Einstein-Maxwell theory and their implications for the weak gravity conjecture. In particular, we show that renormalization of these divergences leads to positivity
Weak Gravity Conjecture and extremal black holes
Motivated by the desire to improve our understanding of the Weak Gravity Conjecture, we compute the one-loop correction of charged particles to the geometry and entropy of extremal black holes in 4D.
Higher-order corrections to mass-charge relation of extremal black holes
We investigate the hypothesis that the higher-derivative corrections always make extremal non-supersymmetric black holes lighter than the classical bound and self-repulsive. This hypothesis was
Black hole entropy function and the attractor mechanism in higher derivative gravity
The entropy of the black hole is given by the value of the entropy function at this extremum, and the values of the scalar fields at the horizon as well as the sizes of AdS2 and SD?2 are determined by extremizing this entropy function with respect to the corresponding parameters.
Charge Orbits of Symmetric Special Geometries and Attractors
We study the critical points of the black hole scalar potential VBH in N = 2, d = 4 supergravity coupled to nV vector multiplets, in an asymptotically flat extremal black hole background described by
Seed for general rotating non-extremal black holes of $\mathcal {N}= 8$ supergravity
We describe the most general asymptotically flat, stationary, non-extremal, dyonic black hole of the four-dimensional supergravity coupled to three vector multiplets that describes the low-energy
Convexity of charged operators in CFTs and the weak gravity conjecture
The Weak Gravity Conjecture is typically stated as a bound on the mass-to-charge ratio of a particle in the theory. Alternatively, it has been proposed that its natural formulation is in terms of the
