Random Walk in the Boundary and Slow Roll in the Bulk
Yoshihisa Kitazawa
The slow rolling inflation is dual to the random walk of conformal zero-mode. The 2 dimensional Fokker-Planck theory predicts the slow roll parameters of 4d inflation theory. The O…
de Sitter Duality and Holographic Renormalization
Yoshihisa Kitazawa
We perform the resummation of the infrared logarithms in the inflationary universe. Applying the renormalization group, we derive the stochastic equations as the effective theory a…
Holographic beta function in de Sitter space
Yoshihisa Kitazawa
The scale invariance of the universe is slightly broken by slow roll parameters. It is likely the slow roll is dual to the random walk. We investigate the distribution function of…
Curvature Perturbations and Anomaly explain Dark Energy
Yoshihisa Kitazawa
We investigate the history of dark energy to explain the present magnitude. We assume the dark energy is the residual cosmological constant. The most important channel in the rehea…
Holographic function in de Sitter space
Hiroyuki Kitamoto, Yoshihisa Kitazawa
We investigate infrared logarithms in de Sitter space from holographic perspective. We employ a gravitational Fokker-Planck equation to investigate the time evolution of the de Sit…
de Sitter duality and logarithmic decay of dark energy
Hiroyuki Kitamoto, Yoshihisa Kitazawa, Takahiko Matsubara
We investigate infrared dynamics of four-dimensional Einstein gravity in de Sitter space. We set up a general framework to investigate dynamical scaling relations in quantum/classi…
