DESCRIPTION:Andrei Barvinsky (Lebedev Physics Institute/CERN)\nWe give an
  overview of the cosmological model driven by conformal field theory (CFT)
  with the initial conditions in the form of the microcanonical density mat
 rix. In particular\, we suggest a new mechanism of hill-top inflation orig
 inating from the underbarrier field oscillations in the vicinity of the in
 flaton potential maxima. Applications of this mechanism\, which might serv
 e as a solution of the string landscape problem\, to Higgs inflation and S
 tarobinsky models are considered. The problem of hierarchy between the inf
 lation and Planck scales is discussed within the concept of a hidden secto
 r of conformal fields with arbitrarily high spins. Thermal corrections to 
 the primordial power spectrum and other properties of this model are brief
 ly discussed.
