Thermal power spectrum in the CFT driven cosmology

Abstract

We present an overview of the recently suggested cosmological model driven by conformal field theory (CFT) with the initial conditions in the form of the microcanonical density matrix. In particular, we discuss the origin of inflationary stage in this model and a novel feature -- the thermal nature of the primordial power spectrum of the CMB anisotropy. The relevant effect of "temperature of the relic temperature anisotropy" can be responsible for a thermal contribution to the red tilt of this spectrum, additional to its conventional vacuum component. The amplification of this effect due to recently established aa-theorem in CFT is briefly discussed.
