Infra-red Cascading During Inflation" (arXiv 0902.0615). Before our work, it was thought that small scale particle creation can not affect large scale cosmological perturbations and the only effect will be changing the background motion of inflaton. This is however incorrect. As you can see in the movie from lattice simulation, $\delta\phi$ is first generated at small scales through $\phi$-$\chi$ scattering. The gradient energy at small scales soon flows to large scales through infra- ...
