How do late-time photons "record" primordial curvature perturbations?
Tomotaka Kuroda, Fumiya Sano, Yusuke Yamada
Inflationary cosmology faces a fundamental gap between primordial quantum fluctuations and the classical cosmic history inferred from observations. Although the primordial quantum…
A consistent formulation of stochastic inflation I: Non-Markovian effects and issues beyond linear perturbations
Diego Cruces, Tomotaka Kuroda
We investigate the origin of non-Markovianity in stochastic inflation and its implications for nonlinear perturbation theory. In the Schwinger--Keldysh formulation, the noise terms…
Numerical simulation of the stochastic formalism including non-Markovianity
Masahiro Kawasaki, Tomotaka Kuroda
We numerically investigate stochastic dynamics in cosmology by solving Langevin equations for Infrared (IR) modes with stochastic noises generated by Ultraviolet (UV) modes at the…
Primordial black holes from a curvaton: the role of bimodal distributions
Tomotaka Kuroda, Atsushi Naruko, Vincent Vennin +1
We investigate the formation of primordial black holes in curvaton models of inflation, where the curvature perturbation is not only generated by the inflaton but also by a light s…
