Kinks are examples of coherent structures: clearly identifiable localized features in a noisy, spatially extended system that can be followed as they move about under the influence of fluctuations.

From kinks to compactonlike kinks
Physical Review E, 1998We show that, in the continuum limit, the generalized \ensuremath{\Phi}-four or double-well model with nonlinear coupling can exhibit compactonlike kink solutions for some specific velocity regimes and when the nonlinear coupling between pendulums is dominant.

Electronic structure of kink and kink-antikink defects in polyacetylene
Physical Review B, 1989The electronic energy levels and charge distribution associated with kink (K) and kink-antikink (K-K\ifmmode\bar\else\textasciimacron\fi{}) defects in polyacetylene have been calculated with use of the first-principles local-density-functional theory.

The kink-phonon and the kink-kink interaction in the Φ4model.
Ferroelectrics, 1980Abstract The kink-phonon and kink-antikink interactions are discussed for the continuum Φ4 equation and its discretized version. Similarities and differences between the two approaches are pointed out. The detailed study of the kink-antikink interaction reveals that under certain conditions a long-lived metastable quasibreather state can exist.

Summary: We show that if a change of spatial topology is mediated by a spacetime with an everywhere-non-singular metric of Lorentzian signature which admits a spinor structure, then the Kervaire semicharacteristic of the boundary plus the kink number of the Lorentzian metric on the boundary must vanish modulo 2. The kink number is a measure of how many

In sufficiently nonlinear field theories there are extended objects whose number is strictly conserved because of continuity of the underlying field as a function of space. We call these kinks. Kinks provide a covariant description of extended but indestructible particles. We give the properties the field theory must possess in order for kinks to exist,

On kinked screw dislocations in the b.c.c. lattice—II. Kink energies and double kinks
Acta Metallurgica, 1983Abstract The self and interaction energies of kinks on screw dislocations in the b.c.c. lattice have been studied by computer simulation, using models representing both potassium and an iron-like material. Both the total energy and the spatial distribution of the energy are considered.
