摘要

Recent cosmic microwave background data favours a blueshifted primeval perturbation spectrum with an indexn＞1, which implies that the equation of state of dominant matter should be such that p + p＜0 during theinflationary expansion of the early universe. We study the quantum Yang-Mills condensate inflationary modeland find that this requirement can be satisfied by the effective quantum Yang-Mills condensate naturally in thestates with the negative dielectric constant.
