Kink-Antikink Interaction Forces and Bound States in a Model with Quadratic and Quartic dispersion
G. A. Tsolias, Robert J. Decker, A. Demirkaya +2
We consider the interaction of solitary waves in a model involving the well-known Klein-Gordon theory, but now bearing both Laplacian and biharmonic terms with different pref…
Jammed disks of two sizes in a narrow channel
Dan Liu, Gerhard Müller
A granular-matter model is exactly solved, where disks of two sizes and weights in alternating sequence are confined to a narrow channel. The axis of the channel is horizontal and…
Almost non-negative scalar curvature on Riemannian manifolds conformal to tori
Brian Allen
In this article we reduce the geometric stability conjecture for the scalar torus rigidity theorem to the conformal case via the Yamabe problem. Then we are able to prove the case…
Kink-Antikink Collisions and Multi-Bounce Resonance Windows in Higher-Order Field Theories
Ivan C. Christov, Robert J. Decker, A. Demirkaya +3
We study collisions of coherent structures in higher-order field-theoretic models, such as the , and ones. The main distinguishing feature, of the example mo…
Kink Dynamics in a Nonlinear Beam Model
Robert J. Decker, Aslihan Demirkaya, Panayotis G. Kevrekidis +3
In this paper, we study the single kink and the kink-antikink collisions of a nonlinear beam equation bearing a fourth-derivative term. We numerically explore some of the key chara…
