Resonance structures in kink-antikink scattering in a quantum vacuum

Mainak Mukhopadhyay, Tanmay Vachaspati

We investigate kink-antikink scattering in the $\lambda {\varphi }^4$ model in the presence of an additional scalar field, $\psi$, that is in its quantum vacuum and interacts with $\varphi$ via a $\xi {\varphi }^2{\psi }^2$…
