"Massless" vector field in de Sitter Universe (2007)
Garidi, T., Rouhani, S., Takook, M. V.
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 light-cone whereas...

Examples of Berezin-Toeplitz Quantization: Finite sets and Unit Interval (2006)
Gazeau, J. P., Garidi, T., Huguet, E., Lachieze-Rey, M., Renaud, J.
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 scheme could reveal...
Krein space quantization in curved and flat spacetimes (2006)
Garidi, T., Huguet, E., Renaud, J.
We re-examine in detail a canonical quantization method à la GuptaBleuler in which the Fock space is built over a so-called Krein space. This method has already been successfully applied to the...

Krein space quantization in curved and flat spacetimes (2004)

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 applied to the...
What is mass in desitterian physics? (2003)
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 conceptual...
De Sitter Waves and the Zero Curvature Limit (2003)
Garidi, T., Huguet, E., Renaud, J.
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 the flat...

Massive Spin-2 Field in De Sitter Space (2003)
Garidi, T., Gazeau, J-P., Takook, M.
In this paper we present a covariant quantization of the ``massive'' spin-2 field on de Sitter (dS) space. By ``massive'' we mean a field which carries a specific principal series representation of...
