A resonance in phonons scattering off a kink in the absence of a Peierls-Nabarro potential

Danial Saadatmand, Arpine Piloyan, David Amundsen +1

We investigate the interaction of small-amplitude waves called phonons, with an initially static kink in an exceptional discretization of the ${\varphi }^4$ model that is free of the Peierl…
