Generating Rotation in a Snap
Soumangsu Chakraborty, Pierre Heidmann, Gela Patashuri
We build a technique to generate rotation from arbitrary static solutions that asymptote to four- or five-dimensional Minkowski spacetime based on Clément's approach [1]. The metho…
Branes and Antibranes in AdS: The Impossible States in the CFT Gap
Roberto Emparan, Pierre Heidmann
We construct a new family of type IIB supergravity solutions corresponding to states of the D1-D5-P-KKm system that carry the same charges and energy as the non-extremal four-charg…
Asymptotically Flat Rotating Topological Stars
Pierre Heidmann, Paolo Pani, Jorge E. Santos
We construct a new class of smooth, horizonless, non-supersymmetric solutions in five-dimensional minimal supergravity, which we call rotating topological stars. Built from a Kerr-…
Tidal Disruption in Topological Solitons and the Emergence of an Effective Horizon
Pierre Heidmann, Gela Patashuri
We compute the dynamics of particles and strings falling into smooth horizonless spacetimes that match the Schwarzschild black hole but replace its horizon with a smooth cap in sup…
Microstates of Non-extremal Black Holes: A New Hope
Soumangsu Chakraborty, Pierre Heidmann
We provide a new roadmap for constructing microstates of non-extremal black holes in supergravity. First, we review the non-linear sigma model of five-dimensional supergravity gove…
Localized Black Holes in AdS: What Happens Below c/12 Stays Below c/12
Iosif Bena, Raphaël Dulac, Pierre Heidmann +1
We construct asymptotically AdSST black holes that are localized on the S and co-exist with the BTZ black hole at small positive energies. These black…
Building the Blocks of Schwarzschild
Raphaël Dulac, Pierre Heidmann
We demonstrate that the Schwarzschild black hole can be ``resolved'' into bound states of Reissner-Nordström black holes in four dimensions. These bound states closely resemble the…
Electromagnetic Entrapment in Gravity
Pierre Heidmann, Madhur Mehta
We derive specific properties of electromagnetism when gravitational effects are not negligible and analyze their impact on new physics at the horizons of black holes. We show that…
Half the Schwarzschild Entropy from Strominger-Vafa Black Holes
Pierre Heidmann
We construct a regular bound state of two extremal black holes in type IIB supergravity with opposite charges. The bound state resembles the Schwarzschild black hole from the asymp…
Geometric Resolution of Schwarzschild Horizon
Ibrahima Bah, Pierre Heidmann
We provide the first example of a geometric transition that resolves the Schwarzschild black hole into a smooth microstructure in eleven-dimensional supergravity on a seven-torus.…
The Uplifton
Iosif Bena, Pierre Heidmann
Almost all proposals to construct de Sitter vacua with a small cosmological constant involve flux compactifications with stabilized moduli. These give AdS vacua, which are uplifted…
Solitonic Excitations in AdS2
Pierre Heidmann, Anthony Houppe
We construct large families of supergravity solutions that are asymptotic to AdS and terminate with a cap that is singular in two dimensions but smooth in higher dimensions. Th…
Non-BPS Bubbling Geometries in AdS
Ibrahima Bah, Pierre Heidmann
We construct large classes of non-BPS smooth horizonless geometries that are asymptotic to AdSST in type IIB supergravity. These geometries are supported by…
Schwarzschild-like Topological Solitons
Ibrahima Bah, Pierre Heidmann, Peter Weck
We construct the first class of topological solitons in gravity that are supported by internal electromagnetic flux with vanishing net charges. The solutions are obtained in a six-…
Stability of topological solitons, and black string to bubble transition
Ibrahima Bah, Anindya Dey, Pierre Heidmann
We study the existence of smooth topological solitons and black strings as locally-stable saddles of the Euclidean gravitational action of five dimensional Einstein-Maxwell theory.…
Non-BPS Floating Branes and Bubbling Geometries
Pierre Heidmann
We derive a non-BPS linear ansatz using the charged Weyl formalism in string and M-theory backgrounds. Generic solutions are static and axially-symmetric with an arbitrary number o…
Bubble Bag End: A Bubbly Resolution of Curvature Singularity
Ibrahima Bah, Pierre Heidmann
We construct a family of smooth charged bubbling solitons in T, four-dimensional Minkowski with a two-torus. The solitons are characterized by a degenerati…
Smooth Bubbling Geometries Without Supersymmetry

We construct the first smooth bubbling geometries using the Weyl formalism. The solutions are obtained from Einstein theory coupled to a two-form gauge field in six dimensions with…
Gravitational Footprints of Black Holes and Their Microstate Geometries
Ibrahima Bah, Iosif Bena, Pierre Heidmann +2
We construct a family of non-supersymmetric extremal black holes and their horizonless microstate geometries in four dimensions. The black holes can have finite angular momentum an…
Topological Stars, Black holes and Generalized Charged Weyl Solutions
Ibrahima Bah, Pierre Heidmann
We construct smooth static bubble solutions, denoted as topological stars, in five-dimensional Einstein-Maxwell theories which are asymptotic to S. The…
Topological Stars and Black Holes
Ibrahima Bah, Pierre Heidmann
We study smooth bubble spacetimes in five-dimensional Einstein-Maxwell theory that resemble four-dimensional magnetic black holes upon Kaluza-Klein reduction. We denote them as Top…
The Great Escape: Tunneling out of Microstate Geometries
Iosif Bena, Felicity Eperon, Pierre Heidmann +1
We compute the quasi-normal frequencies of scalars in asymptotically-flat microstate geometries that have the same charge as a D1-D5-P black hole, but whose long BTZ-like throat en…
Holomorphic Waves of Black Hole Microstructure
Pierre Heidmann, Daniel R. Mayerson, Robert Walker +1
We obtain the largest families constructed to date of -BPS solutions of type IIB supergravity. They have the same charges and mass as supersymmetric D1-D5-P black hol…
