How to (Non-)Perturb a BPS Black Hole

Alberto Castellano, Matteo Zatti

We relate the structure of non-perturbative corrections to BPS black hole observables in flat-spacetime theories with certain properties of probe charged particles in the near-hori…

On Supersymmetric D-brane probes in 4d Attractors

Alberto Castellano, Carmine Montella, Matteo Zatti

We extend the -symmetry analysis of supersymmetric D-brane probes in the attractor geometry, originally performed by Simons, Strominger, Th…

Quantum Calabi-Yau Black Holes and Non-Perturbative D0-brane Effects

Alberto Castellano, Dieter Lüst, Carmine Montella +1

We compute the supersymmetric entropy of the most general BPS black hole in 4d supergravity coupled to vector multiplets obtained from Type IIA string theory…

Exact Path Integral Methods in Supersymmetric Backgrounds

Alberto Castellano, Carmine Montella, Matteo Zatti

We determine the exact functional determinants of charged, massive spin-0 and spin- particles in backgrounds threaded by constant electri…

A note on the Noether-Wald and generalized Komar charges

Tomás Ortín, Matteo Zatti

We propose a simple algorithm to compute the generalized Komar charge of any exactly gauge- and diffeomorphism-invariant theory.

Black Hole Entropy, Quantum Corrections and EFT Transitions

Alberto Castellano, Matteo Zatti

We revisit and study quantum corrections to the supersymmetric entropy of BPS black holes in 4d effective field theories (EFTs), which can be obtained from Type IIA…
