Elastic Kink-Meson Scattering
read the original abstract
In classical field theory, radiation does not reflect off of reflectionless kinks. In quantum field theory, radiation quanta, called mesons, can be reflected. We provide a general analytical formula for the leading order amplitude and probability for the elastic scattering of mesons off of reflectionless quantum kinks. In the case of the Sine-Gordon model we verify that, due to a cancellation of six contributing processes, our general formula yields an amplitude of zero, as is required by integrability.

A resonance in phonons scattering off a kink in the absence of a Peierls-Nabarro potential
In a Peierls-Nabarro-free discrete phi^4 model, phonon scattering off a kink exhibits lattice-spacing-dependent reflection and negative radiation pressure accelerating the kink toward incoming phonons due to resonances.
