We give an overview of the cosmological model driven by conformal field theory (CFT) with the initial conditions in the form of the microcanonical density matrix. In particular, we suggest a new mechanism of hill-top inflation originating from the underbarrier field oscillations in the vicinity of the inflaton potential maxima. Applications of this mechanism, which might serve as a solution of the string landscape problem, to Higgs inflation and Starobinsky models are considered. The problem of hierarchy between the inflation and Planck scales is discussed within the concept of a hidden sector of conformal fields with arbitrarily high spins. Thermal corrections to the primordial power spectrum and other properties of this model are briefly
discussed.
