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 meth…
Fermionic Love of Black Holes in General Relativity
Sumanta Chakraborty, Pierre Heidmann, Paolo Pani
Black holes in General Relativity exhibit a remarkable feature: their response to static scalar, electromagnetic, and gravitational perturbations -- as quantified by the so-called…
The Great Impersonation: -Solitons as Prototypical Black Hole Microstates
Alexandru Dima, Pierre Heidmann, Marco Melis +2
We analyze a new class of static, smooth geometries in five-dimensional supergravity, dubbed -solitons. They carry the same mass and charges as four-dimensional Reissn…
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-…
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…
