Coupled circularly polarized electromagnetic soliton states in magnetized plasmas
G. P. Veldes, N. Lazarides, D. J. Frantzeskakis +1
The interaction between two co-propagating electromagnetic pulses in a magnetized plasma is considered, from first principles, relying on a fluid-Maxwell model. Two circularly pola…
Electrostatic wave interaction via asymmetric vector solitons as precursor to rogue wave formation in non-Maxwellian plasmas
N. Lazarides, Giorgos P. Veldes, D. J. Frantzeskakis +1
An asymmetric pair of coupled nonlinear Schr{ö}dinger (CNLS) equations has been derived through a multiscale perturbation method applied to a plasma fluid model, in which two wavep…
Interactions and dynamics of one-dimensional droplets, bubbles and kinks
G. C. Katsimiga, S. I. Mistakidis, B. A. Malomed +3
We explore the dynamics and interactions of multiple bright droplets and bubbles, as well as the interactions of kinks with droplets and with antikinks, in the extended one-dimensi…
Stationary solitons in F=1 spin-orbit coupled Bose-Einstein condensates
T. Mithun, A. R. Fritsch, G. N. Koutsokostas +3
We consider solitary wave excitations above the ground state of spin-orbit coupled Bose-Einstein condensates (SOBECs). The low energy properties of SOBECs in any of the three…
Two-dimensional rogue waves on zero background of the Davey-Stewartson II equation
Lijuan Guo, Jingsong He, Lihong Wang +3
A prototypical example of a rogue wave structure in a two-dimensional model is presented in the context of the Davey-Stewartson~II (DS~II) equation arising in water waves. The anal…
Ultrashort pulses and short-pulse equations in dimensions
Y. Shen, N. Whitaker, P. G. Kevrekidis +2
In this paper, we derive and study two versions of the short pulse equation (SPE) in dimensions. Using Maxwell's equations as a starting point, and suitable Kramers-Kronig…
Short pulse equations and localized structures in frequency band gaps of nonlinear metamaterials
N. L. Tsitsas, T. P. Horikis, Y. Shen +3
We consider short pulse propagation in nonlinear metamaterials characterized by a weak Kerr-type nonlinearity in their dielectric response. In the frequency "band gaps" (where line…
Vortex Structures Formed by the Interference of Sliced Condensates
R. Carretero-Gonzalez, N. Whitaker, P. G. Kevrekidis +1
We study the formation of vortices, vortex necklaces and vortex ring structures as a result of the interference of higher-dimensional Bose-Einstein condensates (BECs). This study i…
