Query: Quantum optics in different representations of the algebra of canonical
  commutation relations (I): Unexpected properties of Rabi oscillations --
  theory and experiment   We discuss the Jaynes-Cummings model in different representations of the
algebra of canonical commutation relations. The first conclusion is that all
the irreducible representations lead to equivalent physical predictions.
However, the reducible representation recently introduced as a candidate for
`QED without infinities' leads to new effects. We analyze from this perspective
the experiments on Rabi oscillations performed by the Kastler-Brossel
Laboratory group from Paris. Surprisingly, the results seem to support the
reducible representation approach. We also discuss possibilities of more
definitive tests of the new formalism.
