Primordial bispectrum from inflation with background gauge fields
Hiroyuki Funakoshi, Kei Yamamoto
We study the primordial bispectrum of curvature perturbation in the uniform- density slicing generated by the interaction between the inflaton and isotropic background gauge fields…

A Modal Approach to the Numerical Calculation of Primordial non-Gaussianities
Hiroyuki Funakoshi, Sébastien Renaux-Petel
We propose a new method to numerically calculate higher-order correlation functions of primordial fluctuations generated from any early-universe scenario. Our key-starting point is…
