Asymptotically Conically Minkowskian spacetimes from self-gravitating dust
Matteo Fontana, Federico Scali, Sergio Luigi Cacciatori
In this work we investigate some non-Newtonian effects in exact solutions of the Einstein equations, which describe stationary and axisymmetric configurations of self-gravitating d…
Dark Energy
Sergio Luigi Cacciatori, Vittorio Gorini, Federico Re
Among the great mysteries that physics has not yet solved are undoubtedly those of dark energy and dark matter. In this chapter we deal with the first of them. We will expound in d…
Dark Matter
Sergio Luigi Cacciatori, Vittorio Gorini, Federico Re
In this article we address the mystery of dark matter. We expound the various evidences, astrophysical and cosmological, leading to hypothesize the existence of an invisible form o…
Exact solutions for analog Hawking effect in dielectric media
Simone Trevisan, Francesco Belgiorno, Sergio Luigi Cacciatori
In the framework of the analog Hawking radiation for dielectric media, we analyze a toy-model and also the 2D reduction of the Hopfield model for a specific monotone and realistic…
Loops in de Sitter space
Sergio L. Cacciatori, Henri Epstein, Ugo Moschella
We discuss general one and two-loops banana diagrams with arbitrary masses on the de Sitter spacetime by using direct methods of dS quantum field theory in the dimensional regulari…
Tree-Level Superstring Amplitudes: The Neveu-Schwarz Sector
Sergio Luigi Cacciatori, Samuel Grushevsky, Alexander A. Voronov
We present a complete computation of superstring scattering amplitudes at tree level, for the case of Neveu-Schwarz insertions. Mathematically, this is to say that we determine exp…
