Classical Black Hole Probes of UV Scales / Calderón-Infante, José (CERN) ; Delgado, Matilda (Garching, Max Planck Inst. ; Harvard U., Phys. Dept.) ; Li, Yixuan (Padua U. ; INFN, Padua) ; Lust, Dieter (Garching, Max Planck Inst. ; Munich U., ASC) ; Uranga, Angel M. (Madrid, IFT)
In the context of the Swampland program, black hole attractors have been employed to probe infinite distances in moduli space, where the EFT cutoff goes to zero in Planck units and UV effects become significant. [...]

Emergence of Species Scale Black Hole Horizons / Calderón-Infante, José (CERN) ; Delgado, Matilda (Madrid, IFT) ; Uranga, Angel M. (Madrid, IFT)
The scale at which quantum gravity becomes manifest, the species scale $\Lambda_s$, has recently been argued to take values parametrically lower than the Planck scale. We use black holes of vanishing horizon area (small black holes) in effective field theories coupled to quantum gravity to shed light on how the three different physical manifestations of the species scale $\Lambda_s$ relate to each other. [...]

D-instanton and polyinstanton effects from type I' D0-brane loops / Petersson, Christoffer (Chalmers U. Tech.) ; Soler, Pablo (Madrid, IFT) ; Uranga, Angel M. (Madrid, IFT ; CERN)
We study non-perturbative D(-1)-instanton corrections to quartic gauge and curvature couplings in 8d type IIB orientifolds, in terms of a one-loop computation of BPS D0-branes in T-dual type I' models. The complete perturbative and non-perturbative results are determined by the BPS multiplicities of perturbative open strings and D0-brane bound states in the 9d type I' theory. [...]

Non-perturbative effects and wall-crossing from topological strings / Collinucci, Andres (Vienna, Tech. U.) ; Soler, Pablo (Madrid, Autonoma U.) ; Uranga, Angel M. (Madrid, Autonoma U. ; CERN)
We argue that the Gopakumar-Vafa interpretation of the topological string partition function can be used to compute and resum certain non-perturbative brane instanton effects of type II CY compactifications. In particular the topological string A-model encodes the non-perturbative corrections to the hypermultiplet moduli space metric from general D1/D(-1)-brane instantons in 4d N=2 IIB models. [...]

D-brane instantons and the effective field theory of flux compactifications / Uranga, Angel M (CERN ; Madrid, Autonoma U.)
We provide a description of the effects of fluxes on euclidean D-brane instantons purely in terms of the 4d effective action. The effect corresponds to the dressing of the effective non-perturbative 4d effective vertex with 4d flux superpotential interactions, generated when the moduli fields made massive by the flux are integrated out. [...]

Non-perturbative F-terms across lines of BPS stability / Garcia-Etxebarria, Inaki (CERN ; Madrid, Autonoma U.) ; Marchesano, Fernando (CERN) ; Uranga, Angel M. (CERN ; Madrid, Autonoma U.)
We consider non-perturbative terms in the 4d effective action due to BPS D-brane instantons, and study their continuity properties in moduli space as instantons cross lines of BPS stability, potentially becoming non-BPS. We argue that BPS instantons contributing to the superpotential cannot become non-BPS anywhere in moduli space, since they cannot account for the required four goldstino fermion zero modes. [...]

Non-perturbative superpotentials across lines of marginal stability / Garcia-Etxebarria, Inaki (CERN ; Madrid, Autonoma U.) ; Uranga, Angel M. (CERN ; Madrid, Autonoma U.)
We discuss the behaviour of non-perturbative superpotentials in 4d N=1 type II compactifications (and orientifolds thereof) near lines of marginal stability, where the spectrum of contributing BPS D-brane instantons changes discontinuously. The superpotential is nevertheless continuous, in agreement with its holomorphic dependence on the closed string moduli. [...]
