Power-law Modulation of Curvature Perturbation and Primordial Standard Clock

Abstract

In this talk, the speaker will analytically calculate the power spectrum of curvature perturbation modulated by a heavy field with potential ~\phi^n, and show that a power-law modulation is the generic prediction. Furthermore, he finds that such a power-law modulation looks the same as that in the classical standard clock scenario.
