Kink-Kink and Kink-Antikink Interactions with Long-Range Tails. [PDF]
Physical Review Letters, 2018 In this Letter, we address the long-range interaction between kinks and antikinks, as well as kinks and kinks, in φ^{2n+4} field theories for n>1. The kink-antikink interaction is generically attractive, while the kink-kink interaction is generically ...

Stable Kink-Kink and Metastable Kink-Antikink Solutions
Symmetry, Integrability and Geometry: Methods and Applications, 2023 We construct and study two kink theories. One contains a static 2-kink configuration with controllable binding energy. The other contains a locally stable non-topological solution, which we call a lavion.

European Physical Journal C: Particles and FieldsWe describe a one-dimensional kink crystal, which represents a collection of equal and equally localized kinks forming a lattice in the real axis. The results are analytical, original and may motivate other studies on localized structures in high energy ...

Journal of High Energy Physics, 2019 A first order equation for a static ϕ 4 kink in the presence of an impurity is extended into an iterative scheme. At the first iteration, the solution is the standard kink, but at the second iteration the kink impurity generates a kink-antikink solution ...

Journal of High Energy Physics, 2003 We study Born-Infeld type tachyonic effective action of unstable D2-brane with a runaway potential and find rich structure of static regular solitonic solutions. There exists only periodic array of tachyon kink-antikinks in pure tachyonic theory, however, in the presence of electromagnetic fields, solutions include periodic arrays, topological tachyon ...

, 2021 We present the first experimental observation and quantification of the evolution of the three-dimensional (3D) deflection of fibres leading up to kink-band formation in notched unidirectional glass fibre-epoxy composites.

Kink band and shear band localization in anisotropic perfectly plastic solids
, 2021 Shear-driven strain localization has been observed in a wide variety of materials and may take the form of shear bands or kink bands. Based on observations of kink bands in plastically anisotropic metallic nanolaminates and single crystal metals, we ...

Kink instabilities in relativistic jets can drive quasi-periodic radiation signatures [PDF]
, 2020 Relativistic jets are highly collimated plasma outflows emerging from accreting black holes. They are launched with a significant amount of magnetic energy, which can be dissipated to accelerate nonthermal particles and give rise to electromagnetic ...

Topological Photonic Integrated Circuits Based on Valley Kink States [PDF]
Laser & Photonics reviews, 2019 Valley pseudospin, a new degree of freedom in photonic lattices, provides an intriguing way to manipulate photons and enhance the robustness of optical networks.

International Journal of Modern Physics B, 1994 We determine the excitations and S matrix of an integrable isotropic antiferromagnetic quantum spin chain of alternating spin 1/2 and spin 1. There are two types of gapless one-particle excitations: the usual spin 1/2 (“spinor”) kink, and a new spin 0 (“scalar”) kink.
