Le modèle de Davies-Fulling. Un modèle pour la radiation de Hawking.

Abstract : In this thesis, we first consider and then develop the Davies-Fulling model,
which presents strong analogies with Hawking radiation of Black Holes.
This model describes the radiation emitted by a mirror traveling
in Minkowski space-time.
When the trajectory is not inertial, the mirror generates an energy flux,
the properties of which are some functionnals of the trajectory.

In order to recover the salient features of Hawking radiation,
we mainly focussed on uniformly accelerated mirrors,
since they possess a causal horizon.
In order to solve the specifical problems of the Davies-Fulling model in this case,
we have introduced a new model which particularity is to derive from an action principle.
A precise choice of the Lagrangian allows to achieve our goal, namely, to describe
correctly the scattering by the mirror.
Moreover, we have explicited the quantum correlations of the emitted flux by two
different and complementary methods.
