Description
We will discuss some newly found solutions to the full massless semiclassical Einstein equation (SCE) in a cosmological setting (with Λ=0).
After a short introduction to the relevant notions, the SCE is presented in a particular shape which allows for the construction of certain vacuum states. In this setting, the SCE breaks down into an ODE which can be approached numerically and, at least generically, we obtain solutions that well fit physical expectations. Moreover, these solutions indicate dark energy being a quantum effect back-reacting on cosmological metrics and, since in our model m=Λ=0, this may not be traced back to the usual, obvious dark-energy/cosmological constant effect of a quantum field.
