Decoherence and correlations in semiclassical cosmology (Q1805667)

The paper under review continues the study of decoherence and correlation phenomena for the simple cosmological model introduced by the first author in the previous article of the volume [cf. ibid. 38, No. 4, 1333-1348 (1999; Zbl 0983.83055)]. In contrast to the previous reference, the potential that appears in the gravitational action is given here explicitly by the expression \(V(a)=B^2/2\cdot(1-A^2/a^2)\), where \(A,B\) are constants and \(a\) is the Robertson-Walker scale factor.
