Lattice Three-Dimensional Skyrmions Revisited
E. G. Charalampidis, T. A. Ioannidou, P. G. Kevrekidis
In the continuum a skyrmion is a topological nontrivial map between Riemannian manifolds, and a stationary point of a particular energy functional. This paper describes lattice ana…
Time-Periodic Solutions of Driven-Damped Trimer Granular Crystals
E. G. Charalampidis, F. Li, C. Chong +2
In this work, we consider time-periodic structures of trimer granular crystals consisting of alternate chrome steel and tungsten carbide spherical particles yielding a spatial peri…
Vector rogue waves and dark-bright boomeronic solitons in autonomous and non-autonomous settings
R. B. Mareeswaran, E. G. Charalampidis, T. Kanna +2
In this work, we consider the dynamics of vector rogue waves and dark-bright solitons in two-component nonlinear Schrödinger equations with various physically motivated time-depend…
Dark-bright solitons in coupled nonlinear Schrödinger equations with unequal dispersion coefficients
E. G. Charalampidis, P. G. Kevrekidis, D. J. Frantzeskakis +1
We study a two-component nonlinear Schr{ö}dinger system with equal, repulsive cubic interactions and different dispersion coefficients in the two components. We consider states tha…
