Creating kinks with quantum mediation
arXiv:2308.01962 · doi:10.1103/PhysRevD.109.036001
Abstract
We consider the creation of kink-antikink pairs of a scalar field by the scattering of classical wavepackets of a second scalar field, , when there are no direct interactions between and . The creation becomes possible only due to a quantum field that interacts with both and . We scan parameter space and find it favorable for kink production when the initial wavepackets have large total energy and wide spatial extent but scatter at low velocities.
