-induced breathing patterns in multi-component Bose-Einstein condensates
E. G. Charalampidis, Wenlong Wang, P. G. Kevrekidis +2
In this work, we employ the -rotations of a two-component, one-, two- and three-dimensional nonlinear Schrödinger system at and near the Manakov limit, to construct vector s…
Energy criterion for the spectral stability of discrete breathers
Panayotis G. Kevrekidis, Jesús Cuevas-Maraver, Dmitry Pelinovsky
Discrete breathers are ubiquitous structures in nonlinear anharmonic models ranging from the prototypical example of the Fermi-Pasta-Ulam model to Klein-Gordon nonlinear lattices,…
Impulse-induced localized control of chaos in starlike networks
Ricardo Chacón, Faustino Palmero, Jesús Cuevas-Maraver
Locally decreasing the impulse transmitted by periodic pulses is shown to be a reliable method of taming chaos in starlike networks of dissipative nonlinear oscillators, leading to…
A PT-symmetric dual-core system with the sine-Gordon nonlinearity and derivative coupling
J. Cuevas-Maraver, B. A. Malomed, P. G. Kevrekidis
We propose a system of sine-Gordon equations, with the symmetry represented by balanced gain and loss in them. The equations are coupled by sine-field terms and firs…
