"Massless" vector field in de Sitter Universe
T. Garidi, J-P. Gazeau, S. Rouhani +1
In the present work the massless vector field in the de Sitter (dS) space has been quantized. "Massless" is used here by reference to conformal invariance and propagation on the dS…
Krein space quantization in curved and flat spacetimes
T. Garidi, E. Huguet, J. Renaud
We reexamine in detail a canonical quantization method a la Gupta-Bleuler in which the Fock space is built over a so-called Krein space. This method has already been successfully a…
What is mass in desitterian physics?
T. Garidi
In the present paper we discuss the relevance for de Sitter fields of the mass and spin interpretation of the parameters appearing in the theory. We show that these apparently conc…
De Sitter Waves and the Zero Curvature Limit
T. Garidi, E. Huguet, J. Renaud
We show that a particular set of global modes for the massive de Sitter scalar field (the de Sitter waves) allows to manage the group representations and the Fourier transform in t…
Examples of Berezin-Toeplitz Quantization: Finite sets and Unit Interval
J. P. Gazeau, T. Garidi, E. Huguet +2
We present a quantization scheme of an arbitrary measure space based on overcomplete families of states and generalizing the Klauder and the Berezin-Toeplitz approaches. This schem…
Quantization of the sphere with coherent states
Marc Lachieze Rey, Jean-Pierre Gazeau, Eric Huguet +2
Quantization with coherent states allows to " quantize " any space X of parameters. In the case where X is a phase space, this leads to the usual quantum mechanics. But the procedu…
