A Korteweg-de Vries description of dark solitons in polariton superfluids
(Elsevier, 2017)
We study the dynamics of dark solitons in an incoherently pumped exciton-polariton condensate by means of a system composed by a generalized open-dissipative Gross-Pitaevskii equation for the polaritons’ wavefunction and ...

From nodeless clouds and vortices to gray ring solitons and symmetry-broken states in two-dimensional polariton condensates
(2014)
We consider the existence, stability and dynamics of the nodeless state and fundamental nonlinear excitations, such as vortices, for a quasi-two-dimensional polariton condensate in the presence of pumping and nonlinear ...

Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials
(Springer Verlag, 2012)
We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of nonresonant pumping and nonlinear damping. ...

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 ...

Discrete breathers in a nonlinear electric line: modeling, computation, and experiment
(2011)
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 ...

Nonlinear localized modes in two-dimensional electrical lattices
(2013)
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 ...

Generation of localized modes in an electrical lattice using subharmonic driving
(2012)
We show experimentally and numerically that an intrinsic localized mode (ILM) can be stably produced (and experimentally observed) via subharmonic, spatially homogenous driving in the context of a nonlinear electrical ...

Nonlinear excitations, stability inversions, and dissipative dynamics in quasi-one-dimensional polariton condensates
(2011)
We study the existence, stability, and dynamics of the ground state and nonlinear excitations, in the form of dark solitons, for a quasi-one-dimensional polariton condensate in the presence of nonresonant pumping and ...

Supersonic Kinks in Coulomb lattices
(Springer International Publishing, 2014)
There exist in nature examples of lattices of elements for which the interaction is repulsive, the elements are kept in place because different reasons, as border conditions, geometry (e.g., circular) and, certainly, the ...
