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…
Tachyons, Scalar Fields and Cosmology
V. Gorini, A. Yu. Kamenshchik, U. Moschella +1
We study the role that tachyon fields may play in cosmology as compared to the well-established use of minimally coupled scalar fields. We first elaborate on a kind of corresponden…
Decomposing Quantum Fields on Branes
M. Bertola, J. Bros, V. Gorini +2
We provide a method to decompose the two-point function of a quantum field on a warped manifold in terms of fields living on a lower-dimensional manifold. We discuss explicit appli…
Correspondence between Minkowski and de Sitter Quantum Field Theory
Marco Bertola, Vittorio Gorini, Ugo Moschella +1
In this letter we show that the ``preferred'' Klein-Gordon Quantum Field Theories (QFT's) on a d-dimensional de Sitter spacetime can be obtained from a Klein-Gordon QFT on a (d+1)-…
Quantized Temperatures Spectra in Curved Spacetimes
Marco Bertola, Vittorio Gorini, Mauro Zeni
We consider the thermal properties of a scalar field theory on curved spacetimes. In particular, we argue for the existence in the de Sitter, Kruskal and Rindler manifolds of a dis…
