Energy localization and transport in two-dimensional electrical lattices
(NOLTA, 2013)
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 ...

Vortex solutions of the defocusing discrete nonlinear Schroedinger equation
(American Institute of Physics, 2009)
We consider the existence, stability and dynamical evolution of dark vortex states in the two-dimensional defocusing DNLS equation, a model of interest both to atomic physics and to nonlinear optics. Our considerations are ...

Discrete solitons in optical BEC lattices. Effects of n-body interactions
(2006)
In this poster we show some recent results concerning discrete solitons in strong optical lattices, which can be described by the Discrete Nonlinear Schrödinger equation. These results are related to a variation of this ...

Breathers and surface modes in oscillator chains with Hertz ian interactions
(NOLTA, 2012)
We study localized waves in chains of oscillators coupled by Hertzian interactions and trapped in local potentials. This problem is originally motivated by Newton's cradle, a mechanical system consisting of a chain of ...
