# Power-law modulation of the scalar power spectrum from a heavy field with a monomial potential

@article{Huang2018PowerlawMO, title={Power-law modulation of the scalar power spectrum from a heavy field with a monomial potential}, author={Qing Guo Huang and Shi Pi}, journal={Journal of Cosmology and Astroparticle Physics}, year={2018}, volume={2018}, pages={001-001} }

The effects of heavy fields modulate the scalar power spectrum during inflation. We analytically calculate the modulations of the scalar power spectrum from a heavy field with a separable monomial potential, i.e. V(\phi)~\phi^n. In general the modulation is characterized by a power-law oscillation which is reduced to the logarithmic oscillation in the case of n=2.
