Primordial Gravitational Wave- and Curvature Perturbation-Induced Energy Density Perturbations

We study the second-order scalar and density perturbations generated by Gaussian curvature perturbations and primordial gravitational waves in the radiation-dominated era. After presenting all the possible second-order source terms, we obtain the explicit expressions of the kernel functions and the...
