Discrete solitons and vortices in hexagonal and honeycomb lattices: Existence, stability, and dynamics
K. J. H. Law, P. G. Kevrekidis, V. Koukouloyannis +3
We consider a prototypical dynamical lattice model, namely, the discrete nonlinear Schroedinger equation on nonsquare lattice geometries. We present a systematic classification of…

Instability and Evolution of Nonlinearly Interacting Water Waves
P. K. Shukla, I. Kourakis, B. Eliasson +2
We consider the modulational instability of nonlinearly interacting two-dimensional waves in deep water, which are described by a pair of two-dimensional coupled nonlinear Schroedi…

Lagrangean formulation of ion- and dust-ion-acoustic waves
Ioannis Kourakis, Padma Kant Shukla
Ion-acoustic modes propagating in unmagnetized dusty plasmas are studied by applying a generic collisionless fluid model. An Eulerian-to-Lagrangean variable transformation leads to…
