Asymptotic and numerical description of the kink/antikink interaction
Electronic Journal of Differential Equations, 2010 We consider a class of semi-linear wave equations with a small parameter and nonlinearities which provide the equations having exact kink-type solutions.

Current-Driven Kink Instability in Magnetically Dominated Rotating Relativistic Jet
EPJ Web of Conferences, 2013 We have investigated the influence of jet rotation and differential motion on the linear and nonlinear development of the current-driven (CD) kink instability of force-free helical magnetic equilibria via threedimensional relativistic magnetohydrodynamic

Journal of High Energy PhysicsAbstract In classical field theory, radiation does not reflect off of reflectionless kinks. In quantum field theory, radiation quanta, called mesons, can be reflected. We provide a general analytical formula for the leading order amplitude and probability for the elastic scattering of mesons off of reflectionless quantum kinks.

New kink-band formation mechanism discovered in Zn-Al alloy with mille-feuille microstructure
Materials & DesignThe discovery of kink-band strengthening in some Mg-alloys has focused attention on the development of mille-feuille-structured alloys composed of alternating stacks of plate-like soft and hard phases. In this study, we focused on the Zn-6.0mass%Al alloy

Analysis of Kink Reduction in SOI MOSFET Using Selective Back Oxide Structure
Active and Passive Electronic Components, 2012 This paper presents a complete analysis of the kink effect in SOI MOSFET and proposes a method for eliminating kink effect observed in the current-voltage output characteristics of a partially depleted SOI MOSFET device.
