Consistency relations and conservation of in holographic inflation
Jaume Garriga, Yuko Urakawa
It is well known that, in single clock inflation, the curvature perturbation is constant in time on superhorizon scales. In the standard bulk description this follows quite sim…
Relaxion window
Tatsuo Kobayashi, Osamu Seto, Takashi Shimomura +1
We investigate cosmological constraints on the original relaxion scenario proposed by Graham, Kaplan and Rajendran. We first discuss the appropriate sign choice of the terms in the…
Modular invariant inflation
Tatsuo Kobayashi, Daisuke Nitta, Yuko Urakawa
Modular invariance is a striking symmetry in string theory, which may keep stringy corrections under control. In this paper, we investigate a phenomenological consequence of the mo…
