Spontaneous Intrinsic Decoherence in Rabi Oscillations Experiments
We present a simple theoretical description of a recent QED experiment where damping of Rabi oscillations cannot be attributed to environment-induced decoherence (EID). We generalize a previous formalism to describe also nonexponential decay. The possibility of spontaneous intrinsic decoherence (SID), i.e., not due to interaction with environment or fluctuation of some internal parameter but of purely quantum mechanical origin, is discussed. Moreover an experimental cavity QED test of SID is suggested.

- In Ref. a more general expression for P(t,t′) and V (t), depending on two parameters τ1 and τ2 is derived. We choose τ1=τ2=τ because in the experiments considered here, the effective interaction time 〈t’〉=tτ1/τ2 has to coincide with the “laboratory time” t, implying therefore 76-5Google Scholar
