(2005-04-15)The effect of additive noise on a static front that connects a stable homogeneous state with an also stable but spatially periodic state is studied. Numerical simulations show that noise induces front propagation. The ...
-
(American Physical Society, 2015)Ferromagnetic systems under the influence of spin-polarized currents exhibit rich spatiotemporal dynamics at nanoscales. We study spin-transfer nano-oscillators driven by the combination of alternating and direct spin-polarized ...
-
(American Physical Society, 2010)We present an analytic study of traveling fronts, localized colonies, and extended patterns arising from a reaction-diffusion equation which incorporates simultaneously two features: the well-known Allee effect and spatially ...
-
(Elsevier, 2016)Far from equilibrium systems show different states and domain walls between them. These walls, depending on the type of connected equilibria, exhibit a rich spatiotemporal dynamics. Here, we investigate the asymmetrical ...

(American Physical Society, 2015)Out-of-equilibrium systems exhibit domain walls between different states. These walls, depending on the type of connected states, can display rich spatiotemporal dynamics. In this Rapid Communication, we investigate the ...
-
(Amer Chemical Society, 2016)A Berry phase is revealed for circularly polarized light when it is Bragg reflected by a chiral liquid-crystal medium of the same handedness. By using a chiral nematic layer we demonstrate that if the input plane of the ...
-
(2000-10-30)We study the dynamics of bubbles in the one dimensional Cahn-Hilliard equation. For a gas of diluted bubbles we find ordinary differential equations describing their interaction which permits us to describe the ulterior ...
-
(Springer, 2011-03)Development of technologies based on localized states depends on our ability to manipulate and control these nonlinear structures. In order to achieve this, the interactions between localized states and control tools should ...
-
(Amer Physical Soc, 2020)Mobility properties of spatially localized structures arising from chaotic but deterministic forcing of the bistable Swift-Hohenberg equation are studied and compared with the corresponding results when the chaotic forcing ...
-
(Elsevier B.V., 2019)© 2019 Elsevier B.V. Driven nano-magnets have attracted increasing attention due to their potential applications and complex dynamical behavior. Spin valves are possibly the most studied driven nano-magnets because applied ...
-
(2013)Employing nematic liquid crystals in a homeotropic cell with a photosensitive wall, dissipative vortex pairs are selectively induced by external illumination and the interaction law is characterized for pairs of ...
-
(American Institute of Physics Inc., 2018)Coupled nonlinear oscillators can present complex spatiotemporal behaviors. Here, we report the coexistence of coherent and incoherent domains, called chimera states, in an array of identical Duffing oscillators coupled ...
-
(Optical Society of America, 2017)We consider coupled-waveguide resonators subject to optical injection. The dynamics of this simple device are described by the discrete Lugiato-Lefever equation. We show that chimera-like states can be stabilized, thanks ...
-
(Amer Physical Soc, 2016)Coupled oscillators can exhibit complex self-organization behavior such as phase turbulence, spatiotemporal intermittency, and chimera states. The latter corresponds to a coexistence of coherent and incoherent states ...
-
(2005)The dynamics of one-dimensional Cahn-Hilliard model is studied. The stationary and particle-type solutions, the bubbles, are perused as a function of initial conditions, boundary conditions, and system size. We characterize the ...
-
(American Institute of Physics, 2020)The characterization of equilibria and their transition is fundamental in dynamic systems. Experimentally, the characterization of transitions is complex due to time scales separation, the effect of thermal fluctuations, ...

(Universidad de ChilePrograma Cybertesis, 2007)El presente trabajo trata sobre un estudio experimental de la dinámica de una capa granular delgada cuasi unidimensional, fluidizada vía un flujo gaseoso modulado periódicamente en el tiempo, con énfasis en las transiciones ...

Dissipative magnetization textures induced by spin-transfer torques and alternating magnetic fields (Universidad de Chile, 2016)Los materiales ferromagnéticos a escala nanométrica pueden ser manipulados mediante torques por transferencia de espín y/o campos magnéticos oscilatorios. El torque por transferencia de espín es el resultado de la interacción ...
