Horizons cannot save the Landscape
Iosif Bena, Alex Buchel, Oscar J. C. Dias
Solutions with anti-D3 branes in a Klebanov-Strassler geometry with positive charge dissolved in fluxes have a certain singularity corresponding to a diverging energy density of th…
Polchinski-Strassler does not uplift Klebanov-Strassler
Iosif Bena, Mariana Grana, Stanislav Kuperstein +1
Anti-D3-branes at the tip of the Klebanov-Strassler solution with D3-charge dissolved in fluxes give rise, in the probe approximation, to a metastable state. The fully back-reacted…
Non-extremal Black Hole Microstates: Fuzzballs of Fire or Fuzzballs of Fuzz ?
Iosif Bena, Andrea Puhm, Bert Vercnocke
We construct the first family of microstate geometries of near-extremal black holes, by placing metastable supertubes inside certain scaling supersymmetric smooth microstate geomet…
Black Holes and Fourfolds
Iosif Bena, Hagen Triendl, Bert Vercnocke
We establish the relation between the structure governing supersymmetric and non-supersymmetric four- and five-dimensional black holes and multicenter solutions and Calabi-Yau flux…
Anti-D3's - Singular to the Bitter End
Iosif Bena, Mariana Grana, Stanislav Kuperstein +1
We study the full backreaction of anti-D3 branes smeared over the tip of the deformed conifold. Requiring the 5-form flux and warp factor at the tip to be that of anti-D3 branes, w…
Scaling BPS Solutions and pure-Higgs States
Iosif Bena, Micha Berkooz, Jan de Boer +2
Depending on the value of the coupling, BPS states of type II string theory compactified on a Calabi-Yau manifold can be described as multicenter supergravity solutions or as state…
Persistent anti-brane singularities
Iosif Bena, Daniel Junghans, Stanislav Kuperstein +3
Anti-D-branes inserted in warped throat geometries (supported by fluxes that carry D-brane charges) develop unphysical singularities. It has been argued that these singularities co…
Un-twisting the NHEK with spectral flows
Iosif Bena, Monica Guica, Wei Song
We show that the six-dimensional uplift of the five-dimensional Near-Horizon-Extremal-Kerr (NHEK) spacetime can be obtained from an AdS_3 X S^3 solution by a sequence of supergravi…
