Abstract

Macroscopic extended systems with dissipation and injection of energy can exhibit particlelike solutions. Dissipative kinks with an oscillatory cloak and a family of localized states that connect uniform symmetric states in a magnetic wire forced with a transversal oscillatory magnetic field and in a parametrically driven damped pendula chain are studied. The oscillatory cloak is composed of evanescent waves emitted at the kink position and generated by a resonant mechanism. These waves mediate the kink interaction and generate a family of localized states.
