Supersymmetry of the static Reissner-Nordström black hole in Bertotti-Robinson ()
Andrea Di Pinto, Adriano Viganò
We examine supersymmetry of charged and accelerating black holes embedded in a Bertotti-Robinson universe, in the context of , supergravity. After a review of the soluti…
Bubbles of nothing in binary black holes and black rings, and viceversa
Marco Astorino, Roberto Emparan, Adriano Viganò
We argue that expanding bubbles of nothing are a widespread feature of systems of black holes with multiple or non-spherical horizons, appearing as a limit of regions that are narr…
AdS-Taub-NUT spacetimes and exact black bounces with scalar hair
José Barrientos, Adolfo Cisterna, Nicolás Mora +1
We present a new family of exact four-dimensional Taub-NUT spacetimes in Einstein- theory supplemented with a conformally coupled scalar field exhibiting a power-counting super-…
Supersymmetric black holes with spiky horizons
Federico Faedo, Silke Klemm, Adriano Viganò
We use the recipe of arXiv:1003.2974 to find half-BPS near-horizon geometries in the t model of , gauged supergravity, and explicitely construct some new examples. A…
Quantization and soliton-like solutions for the -model in a optic fiber
Francesco Belgiorno, Sergio Luigi Cacciatori, Simone Trevisan +1
In the framework of a mesoscopical model for dielectric media we provide an analytical description for the electromagnetic field confined in a cylindrical cavity containing a finit…
On spinorial representations of involutory subalgebras of Kac-Moody algebras
Axel Kleinschmidt, Hermann Nicolai, Adriano Viganò
The representation theory of involutory (or 'maximal compact') subalgebras of infinite-dimensional Kac-Moody algebras is largely terra incognita, especially with regard to fermioni…
Spectral boundary conditions and solitonic solutions in a classical Sellmeier dielectric
F. Belgiorno, S. L. Cacciatori, A. Viganò
Electromagnetic field interactions in a dielectric medium represent a longstanding field of investigation, both at the classical level and at the quantum one. We propose a 1+1 dime…
