The Swampland program aims to distinguish effective theories which can be completed into
quantum gravity in the ultraviolet from those which cannot. This article forms an introduction …

A bstract We discuss aspects of the possible transition between small black holes and highly
excited fundamental strings. We focus on the connection between black holes and the self …

We obtain a black hole solution in the Einstein–Gauss–Bonnet theory for the string cloud
model in a five-dimensional spacetime. We analyze the event horizons and naked …

A bstract We compute the first-order α′ corrections to a family of 4-dimensional, 4-charge,
non-extremal black hole solutions of Heterotic Supergravity in the case with 3 independent …

A bstract In recent literature, it has been argued that a mild form of the Weak Gravity
Conjecture (WGC) is satisfied by wide classes of effective field theories in which higher …

A bstract We find solutions of the heterotic string effective action describing the first-order α′
corrections to two-charge black holes at finite temperature. Making explicit use of these …

We carry out the holographic renormalization of Einstein-Maxwell theory with curvature-
squared corrections. In particular, we demonstrate how to construct the generalized Gibbons …

This paper focuses on the possible correlation between conjectures KSS bound and weak
gravity conjecture (WGC). The hydrodynamic values KSS bound and weak gravity …

A bstract We study scattering of minimally coupled massless scalar fields by non-extremal
spherically symmetric black holes in d dimensions with string-theoretical α′ corrections. We …

We solve the dilaton field equation in the background of a spherically symmetric black hole
in bosonic or heterotic string theory with curvature-squared corrections in arbitrary d …
