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…
De Sitter magnetic black hole dipole with a supersymmetric horizon
Sergio Luigi Cacciatori, Davide Astesiano
We find a new non BPS solution in gauged supergravity coupled to gauge fields and matter. It consists in a closed universe with two extremal black holes of equal…
On Generalized Lemaitre-Tolman-Bondi Metric. Fractal Matter at the end of Matter-Antimatter Recombination
Sergio Cacciatori, Alessio Marrani, Federico Re
Many recent researches have investigated the deviations from the Friedmannian cosmological model, as well as their consequences on unexplained cosmological phenomena, such as dark…
Analytic SU(N) Skyrmions at finite Baryon density
Pedro D. Alvarez, Sergio L. Cacciatori, Fabrizio Canfora +1
We construct analytic (3+1)-dimensional Skyrmions living at finite Baryon density in the SU(N) Skyrme model that are not trivial embeddings of SU(2) into SU(N). We used Euler angle…
Optical theorem and effective action: new proofs of old results in QFT
Sergio L. Cacciatori, Andrea Zanzi
A new proof of the optical theorem at all orders is presented. Although the theorem is a well-known result in Quantum Field Theory, our proof is interesting because it is particula…
Gravitational waves, 100 years later
Sergio L. Cacciatori
We present a short communication on the recent direct measurements of gravitational waves, made possible by the joint efforts of the LIGO and the Virgo projects. These notes are de…
The Universal de Rham/Spencer Double Complex on a Supermanifold
Sergio L. Cacciatori, Simone Noja, Riccardo Re
The universal Spencer and de Rham complexes of sheaves over a smooth or analytical manifold are well known to play a basic role in the theory of -modules. In this arti…
Super throats with non trivial scalars
Davide Astesiano, Sergio Luigi Cacciatori
We find new BPS solutions in Fayet-Iliopoulos gauged supergravity with STU prepotential. These are stationary solutions carrying a Kerr-Newman throat spacetime geometry…
Analogue Hawking Effect: BEC and Surface Waves
F. Belgiorno, S. L. Cacciatori, A. Farahat +1
We take into account two further physical models which play an utmost importance in the framework of Analogue Gravity. We first consider Bose--Einstein condensates (BEC) and then s…
Analogue Hawking Effect: a master equation
F. Belgiorno, S. L. Cacciatori, A. Viganò
We consider further on the problem of the analogue Hawking radiation. We propose a fourth order ordinary differential equation, which allows to discuss the problem of Hawking radia…
