Quantum Effects for the Dirac Field in Reissner-Nordstrom-AdS Black Hole Background
F. Belgiorno, S. L. Cacciatori
The behavior of a charged massive Dirac field on a Reissner-Nordstrom-AdS black hole background is investigated. The essential self-adjointness of the Dirac Hamiltonian is studied.…
Mapping the geometry of the E6 group
Fabio Bernardoni, Sergio L. Cacciatori, Bianca L. Cerchiai +1
In this paper we present a construction for the compact form of the exceptional Lie group E6 by exponentiating the corresponding Lie algebra e6, which we realize as the the sum of…
Conservation laws and scattering for de Sitter classical particles
S. Cacciatori, V. Gorini, A. Kamenshchik +1
Starting from an intrinsic geometric characterization of de Sitter timelike and lightlike geodesics we give a new description of the conserved quantities associated with classical…
Two loop superstring amplitudes and S_6 representations
Sergio Cacciatori, Francesco Dalla Piazza
In this paper we describe how representation theory of groups can be used to shorten the derivation of two loop partition functions in string theory, giving an intrinsic descriptio…
Geometry of four-dimensional Killing spinors
S. L. Cacciatori, M. M. Caldarelli, D. Klemm +2
The supersymmetric solutions of N=2, D=4 minimal ungauged and gauged supergravity are classified according to the fraction of preserved supersymmetry using spinorial geometry techn…
