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…
Cavity effect in the quasinormal mode spectrum of topological stars
Pierre Heidmann, Nicholas Speeney, Emanuele Berti +1
We study scalar perturbations of topological solitons, smooth horizonless solutions in five-dimensional Einstein-Maxwell theory that correspond to coherent states of gravity via th…
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.…
