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…

No-go theorem of anisotropic inflation via Schwinger mechanism
Hiroyuki Kitamoto
In the presence of a dilatonic coupling between an inflaton and a gauge field, a persistent electric field (i.e., an anisotropic inflation) is obtained as a solution of the…

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…
