Abstract

In a periodically driven nonlinear lattice, small lattice deformations are parametrically amplified and the dynamic phonon response function is broadly enhanced. As a consequence, the phonon-mediated electron-electron attraction becomes stronger, allowing Cooper pairs to be formed at higher temperatures.
