(Anti-)Stokes Scattering on Kinks

At leading order, there are three inelastic scattering processes beginning with a quantum kink and a fundamental meson. Meson multiplication, in which the final state is a kink and two mesons, was

A Reduced Inner Product for Kink States

Solitons in classical field theories correspond to states in quantum field theories. If the spatial dimension is infinite, then momentum eigenstates are not normalizable. This leads to infrared



Degeneracy and Kink Scattering in a Two Coupled Scalar Field Model in (1,1) Dimensions

In this work, we consider the model of two coupled scalar fields φ, χ in (1, 1) dimensions introduced by D. Bazeia, M. J. dos Santos, and R. F. Ribeiro, Phys. Lett. A 208, 84 (1995). The model has a

Kink-antikink collisions in the periodic φ4 model

Exciting the domain wall soliton

Many solitonic configurations in field theory have localized bound states in their spectrum of linear perturbations. This opens up the possibility of having long lived excitations of these solitons

Model for clustering of living species

This work describes a model composed of a set of female and male individuals that obeys simple rules that rapidly transform an uniform initial state into a single cluster that evolves in time as a stable dynamical structure and shows that the center of mass of the structure moves as a random walk.
