Boundary scattering in the ϕ4 model.

Dorey, Patrick and Halavanau, Aliaksei and Mercer, James and Romanczukiewicz, Tomasz and Shnir, Yasha (2017) 'Boundary scattering in the ϕ4 model.', Journal of high energy physics., 2017 (5). p. 107.


We study boundary scattering in the ϕ4 model on a half-line with a oneparameter family of Neumann-type boundary conditions. A rich variety of phenomena is observed, which extends previously-studied behaviour on the full line to include regimes of near-elastic scattering, the restoration of a missing scattering window, and the creation of a kink or oscillon through the collision-induced decay of a metastable boundary state. We also study the decay of the vibrational boundary mode, and explore different scenarios for its relaxation and for the creation of kinks.
