    "abstract": "We consider the interaction of an harmonic oscillator with the quantum field\nvia radiation pressure. We show that a `Schrodinger cat\u0027 state decoheres in a\ntime scale that depends on the degree of `classicality\u0027 of the state\ncomponents, and which may be much shorter than the relaxation time scale\nassociated to the dynamical Casimir effect. We also show that decoherence is a\nconsequence of the entanglement between the quantum states of the oscillator\nand field two-photon states. With the help of the fluctuation-dissipation\ntheorem, we derive a relation between decoherence and damping rates valid for\narbitrary values of the temperature of the field. Coherent states are selected\nby the interaction as pointer states.",
