Modular anomaly of BPS black holes

open access: yesJournal of High Energy Physics
Generating functions of BPS indices, counting states of D4-D2-D0 black holes in Calabi-Yau compactifications of type IIA string theory and identified with rank 0 Donaldson-Thomas invariants, are examples of mock modular forms.

Kalb-Ramond field, black holes and black strings in (2 + 1)D [PDF]

open access: yesarXiv
New rotating dilaton black hole and black string solutions in three spacetime dimensions are obtained. The background spacetime interpolates between Anti-de Sitter and a (an asymptotically) flat spacetime. The new black strings are characterized by their masses, angular momenta and axion charges.

Charge (in)stability and superradiance of Topological Stars

open access: yesJournal of High Energy Physics
We study linear massive scalar charged perturbations of Topological Stars in the fuzzball and in the black hole (Black String) regimes. The objects that naturally couple to the electric 3-form field strength of these solutions are charged strings, wound ...
