From CFT Spectra to CMB Multipoles in Quantum Gravity Cosmology

Ken-ji Hamada, Shinichi Horata, Tetsuyuki Yukawa

We study the inflation process of universe based on the renormalizable quantum gravity formulated as a conformal field theory (CFT). We show that the power-law CFT spectrum approac…

Making a Universe

Shinichi Horata, Tetsuyuki Yukawa

For understanding the origin of anisotropies in the cosmic microwave background, rules to construct a quantized universe is proposed based on the dynamical triangulation method of…

Space-time Evolution and CMB Anisotropies from Quantum Gravity

Ken-ji Hamada, Shinichi Horata, Tetsuyuki Yukawa

We propose an evolutional scenario of the universe which starts from quantum states with conformal invariance, passing through the inflationary era, and then makes transition to th…

Conformal Algebra and Physical States in Non-critical 3-brane on R*S^3

Ken-ji Hamada, Shinichi Horata

A world-volume model of non-critical 3-brane is quantized in a strong coupling phase where fluctuations of the conformal mode become dominant. This phase, called the conformal-mode…
