Characterization of spatiotemporal chaos in a Kerr optical frequency comb and in all fiber cavities (OSA - The Optical Society, 2017)Complex spatiotemporal dynamics have been a subject of recent experimental investigations in optical frequency comb microresonators and in driven fiber cavities with Kerr-type media. We show that this complex behavior has ...

(American Physical Society, 2014)Macroscopic magnetic systems subjected to external forcing exhibit complex spatiotemporal behaviors as result of dissipative self-organization. Pattern formation from a uniform magnetization state, induced by the combination ...
-
(American Institute of Physics Inc., 2017)Time-delayed feedback plays an important role in the dynamics of spatially extended systems. In this contribution, we consider the generic Lugiato-Lefever model with delay feedback that describes Kerr optical frequency ...
-
(2012)Nonequilibrium localized states under the influence of translational coupling are studied experimentally and theoretically. We show that localized structures are deformed and advected in the direction of the coupling, ...

Experimental observation of front propagation in a negatively diffractive inhomogeneous Kerr cavity (American Physical Society, 2014)A focusing Kerr Fabry-P´erot cavity operating in a negative diffraction regime exhibits transverse propagating fronts connecting two different nematic liquid crystal molecule average orientations. Under an inhomogeneous spatial ...
-
(American Physical Society, 2019)Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic ...
-
(OSA - The Optical Society, 2019)Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. ...

(American Physical Society, 2019)We report experimental and theoretical results on the lateral wet oxidation of bidimensional thin aluminum-rich layers into AlOx. We introduce a reaction-diffusion model of oxidation front propagation that includes effects ...
-
(Universidad de Chile, 2018)En esta tesis se presenta un estudio de la reología y de las estructuras espaciales que surgen en suspensiones de bacterias en el regimen semi-diluido. Debido al tamaño microscópico de las bacterias, su densidad y velocidad ...
-
(American Physical Society, 2017)Multistable systems exhibit a rich front dynamics between equilibria. In one-dimensional scalar gradient systems, the spread of the fronts is proportional to the energy difference between equilibria. Fronts spreading p ...
