Title：

Moduli-dependent one-loop entropy of hyperbolic BPS black hole in AdS4

Abstract:

We study one-loop logarithmic corrections to the entropy of static hyperbolic BPS black holes in asymptotically AdS4 spacetime within N=2 Fayet–Iliopoulos gauged supergravity. In this setup, the classical BPS attractor mechanism exhibits flat directions, leaving scalar moduli on the horizon unfixed while the Bekenstein–Hawking entropy depends only on the charges. We show that quantum corrections induce a nontrivial dependence of the entropy on the horizon moduli, generating an effective quantum potential that dynamically stabilizes them. This provides an explicit realization of the quantum lifting of classical attractor flat directions. We will also comment on implications for the quantum structure of AdS black holes and possible connections to holography.
