# The cosmological vector modes from a monochromatic primordial power spectrum

@inproceedings{Chang2022TheCV, title={The cosmological vector modes from a monochromatic primordial power spectrum}, author={Zhe Chang and Xukun Zhang and Jinghua Zhou}, year={2022} }

. The cosmological background of higher order vector modes can be generated by the ﬁrst order scalar perturbations. We investigate the second order and the third order vector modes systematically. The explicit expressions of two point functions (cid:104) V ( n ) ,λ V ( n ) ,λ (cid:48) (cid:105) ( n = 2 , 3) and power spectra corresponded are presented. In the case of a monochromatic primordial power spectrum, the second order vector modes do not exist. However, the third order vector modes can…
