DESCRIPTION:Speakers: Nicolai Rothe (rothe@math.tu-berlin.de)\n\nWe will d
 iscuss some newly found solutions to the full massless semiclassical Einst
 ein equation (SCE) in a cosmological setting (with Λ=0).\nAfter a short i
 ntroduction 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 numeric
 ally and\, at least generically\, we obtain solutions that well fit physic
 al expectations. Moreover\, these solutions indicate dark energy being a q
 uantum effect back-reacting on cosmological metrics and\, since in our mod
 el m=Λ=0\, this may not be traced back to the usual\, obvious dark-energy
 /cosmological constant effect of a quantum field.\n\nhttps://indico.tpi.un
