Zooming out of AdSSS: The Branes behind the CFT's

Iosif Bena, Antoine Bourget, Raphaël Dulac +2

We reveal the supersymmetric brane configurations that give rise to AdSSS supergravity solutions, which are holographic duals to three-dimensional CFT…

Effervescent Spikes in M-theory

Iosif Bena, Raphaël Dulac, Dimitrios Toulikas +1

AdS S S solutions warped over a Riemann surface, , are indexed by a parameter, , that defines the superconformal algebra, $D(2,1; γ) \oplus D(2,1…

Positive Spin-induced Quadrupole Moment in String Theory

Iosif Bena, Angèle Lochet

We identify singularity-free Running-Kerr-Taub-Bolt solutions of eleven-dimensional supergravity that descend to four-dimensional rotating solutions with flat-space asymptotics. We…

Effective Microstructure

Iosif Bena, Raphaël Dulac, Emil J. Martinec +3

In AdS/CFT duality, there are large families of smooth, horizonless microstate geometries that correspond to heavy pure states of the dual CFT. The metric and fluxes are co…

Microstate Geometries

Iosif Bena, Nicholas P. Warner

We review the 20-year history of the Microstate Geometry Programme and the essential role that supergravity has played, and will continue to play, in the description of black-hole…

Maze Topiary in Supergravity

Iosif Bena, Anthony Houppe, Dimitrios Toulikas +1

We show that the supergravity solutions for 1/4-BPS intersecting systems of M2 and M5 branes are completely characterized by a single ``maze'' function that satisfies a non-linear…
