Numerical study of two-dimensional disordered Klein-Gordon lattices with cubic soft anharmonicity [Article]
Localized oscillations appear both in ordered nonlinear lattices (breathers) and in disordered linear lattices (Anderson modes). Numerical studies on a class of two-dimensional systems of the Klein-Gordon type show that ...
Localized oscillations in nonlinear hamiltonian Klein-Gordon lattices. Breathers and Anderson modes [Presentation]
There are two different sources of localization in discrete lattices: • Anderson modes in disordered harmonic lattices  • Discrete breathers in homogeneous nonlinear lattices 
Interaction of moving breathers with an impurity [Presentation]
(World Scientific, 2003)
We analyze the influence of an impurity in the evolution of moving discrete breathers in a Klein–Gordon chain with non-weak nonlinearity. Three different behaviours can be observed when moving breathers interact with the ...
Discrete breathers in a nonlinear electric line: modeling, computation, and experiment [Article]
We study experimentally and numerically the existence and stability properties of discrete breathers in a periodic nonlinear electric line. The electric line is composed of single cell nodes, containing a varactor diode ...
Solitons in one-dimensional nonlinear Schrödinger lattices with a local inhomogeneity [Article]
In this paper we analyze the existence, stability, dynamical formation, and mobility properties of localized solutions in a one-dimensional system described by the discrete nonlinear Schrödinger equation with a linear point ...
Nonlinear localized modes in two-dimensional electrical lattices [Article]
We report the observation of spontaneous localization of energy in two spatial dimensions in the context of nonlinear electrical lattices. Both stationary and moving self-localized modes were generated experimentally and ...
Energy localization and transport in two-dimensional electrical lattices [Presentation]
Intrinsic localized modes (ILMs) have been generated and characterized in two-dimensional nonlinear electrical lattices which were driven by a spatially-uniform voltage signal. These ILMs were found ...
Impulse-induced localized control of chaos in starlike networks [Article]
(American Physical Society, 2016)
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 both synchronous periodic states ...
Moving breathers in a bent DNA model [Article]
We study the properties of moving breathers in a bent DNA model with short range interaction, due to the stacking of the base pairs, and long range interaction, due to the finite dipole moment of the bonds within each ...
Moving discrete breathers in a Klein–Gordon chain with an impurity [Article]
We analyse the influence of an impurity in the evolution of moving discrete breathers in a Klein–Gordon chain with non-weak nonlinearity. Three different types of behaviour can be observed when moving breathers interact ...
