Massive Dirac particles on the background of charged de-Sitter black hole manifolds
F. Belgiorno, S. L. Cacciatori
We consider the behavior of massive Dirac fields on the background of a charged de-Sitter black hole. All black hole geometries are taken into account, including the Reissner-Nords…
Absence of Normalizable Time-periodic Solutions for The Dirac Equation in Kerr-Newman-dS Black Hole Background
Francesco Belgiorno, Sergio L. Cacciatori
We consider the Dirac equation on the background of a Kerr-Newman-de Sitter black hole. By performing variable separation, we show that there exists no time-periodic and normalizab…
D-Branes on C^3_6 part I: prepotential and GW-invariants
Sergio Luigi Cacciatori, Marco Compagnoni
This is the first of a set of papers having the aim to provide a detailed description of brane configurations on a family of noncompact threedimensional Calabi-Yau manifolds. The s…
Special Relativity in the 21 century
S. Cacciatori, V. Gorini, A. Kamenshchik
This paper, which is meant to be a tribute to Minkowski's geometrical insight, rests on the idea that the basic observed symmetries of spacetime homogeneity and of isotropy of spac…
Genus four superstring measures
Sergio L. Cacciatori, Francesco Dalla Piazza, Bert van Geemen
A main issue in superstring theory are the superstring measures. D'Hoker and Phong showed that for genus two these reduce to measures on the moduli space of curves which are determ…
Renormalized Thermal Entropy in Field Theory
Sergio Cacciatori, Fabio Costa, Federico Piazza
Standard entropy calculations in quantum field theory, when applied to a subsystem of definite volume, exhibit area-dependent UV divergences that make a thermodynamic interpretatio…
The Dirac Equation in Kerr-Newman-AdS Black Hole Background
Francesco Belgiorno, Sergio L. Cacciatori
We consider the Dirac equation on the Kerr-Newman-AdS black hole background. We first perform the variable separation for the Dirac equation and define the Hamiltonian operator $\h…
On the role of the far fields and of cosmology for the theory of gravitation and for the dark matter problem
A. Carati, S. L. Cacciatori, L. Galgani
We give an estimate of the gravitational field of force exerted on a test particle by the far galaxies, in the frame of the weak field approximation. In virtue of Hubble's law, the…
Modular Forms and Three Loop Superstring Amplitudes
Sergio L. Cacciatori, Francesco Dalla Piazza, Bert van Geemen
We study a proposal of D'Hoker and Phong for the chiral superstring measure for genus three. A minor modification of the constraints they impose on certain Siegel modular forms lea…
