Dissipative breathers in rf SQUID metamaterials
George P. Tsironis, Nikos Lazarides, Maria Eleftheriou
The existence and stability of dissipative breathers in rf SQUID (Superconducting Quantum Interference Device) arrays is investigated numerically. In such arrays, the nonlinearity…
Multistability and localization in coupled nonlinear split-ring resonators
Nikos Lazarides, Mario I. Molina, George P. Tsironis +1
We study the dynamics of a pair of nonlinear split-ring resonators (a `metadimer') excited by an alternating magnetic field and coupled magnetically. Linear metadimers of this kind…
Discrete nonlinear Schrödinger equation in complex networks
F. Perakis, G. P. Tsironis
We investigate dynamical aspects of the discrete nonlinear Schrödinger equation (DNLS) in finite lattices. Starting from a periodic chain with nearest neighbor interactions, we ins…
Bulk and surface magnetoinductive breathers in binary metamaterials
M. I. Molina, N. Lazarides, G. P. Tsironis
We study theoretically the existence of bulk and surface discrete breathers in a one-dimensional magnetic metamaterial comprised of a periodic binary array of split-ring resonators…
Surface magnetoinductive breathers in two-dimensional magnetic metamaterials
Maria Eleftheriou, Nikos Lazarides, George P. Tsironis +1
We study discrete surface breathers in two-dimensional lattices of inductively-coupled split-ring resonators with capacitive nonlinearity. We consider both Hamiltonian and dissipat…
Extreme events in discrete nonlinear lattices
A. Maluckov, Lj. Hadzievski, N. Lazarides +1
We perform statistical analysis on discrete nonlinear waves generated though modulational instability in the context of the Salerno model that interpolates between the intergable A…
