Andrade Silva, Ignacio Javier; Bortolozzo, Umberto; Castillo Pinto, Camila; Clerc Gavilán, Marcel; González Cortés, Gregorio; Residori, S.; Wilson, Mario (Royal Society Publishing, 2018)Order–disorder phase transitions driven by temperature or light in soft matter materials exhibit complex dissipative structures. Here, we investigate the spatio-temporal phenomena induced by light in a dye-doped nematic ...

Contreras Contreras, Diego Andrés (Universidad de Chile, 2015)El objetivo principal de esta tesis fue estudiar el efecto del ruido interno en el límite de baja intensidad sobre patrones y paredes de dominio entre estados simétricos, particularmente analizando como afecta el ruido a ...
-
Campo Rojas, Francisco Daniel del (Universidad de Chile, 2013)El objetivo de esta tesis fue estudiar y caracterizar los efectos del acomplamiento traslacional y del ruido, sobre estados localizados y soluciones periódicas (o patrones) en sistemas macroscópicos. En el contexto de un ...

Franco Gómez, Andrés Fernando (Universidad de Chile, 2012)Este trabajo se dedica a la medición de la estadística espacial de la Turbulencia de Ondas Capilares, que puede ser definida como un sistema estadístico fuera del equilibrio de ondas aleatorias no lineales. El trabajo ...

Clerc Gavilán, Marcel; González Cortes, Gregorio; Wilson, Mario (Optical Soc. Amer., 2016-06-15)Extreme events such as rogue waves are often associated with the merging of coherent structures. We report on experimental results in the physics of extreme events emerging in a liquid-crystal light valve subjected to ...

Verschueren Van Rees, Nicolás (Universidad de Chile, 2013)El objetivo de esta Tesis es dar una descripción sobre los comportamientos no variacionales mostrados por sistemas extendidos que presentan patrones como soluciones de equilibrio. En particular, se estudiaron dos fenómenos ...
-
Berríos Caro, Ernesto; Clerc Gavilán, Marcel; León, A. O. (American Physical Society, 2016)Macroscopic extended systems with dissipation and injection of energy can exhibit particlelike solutions. Dissipative kinks with an oscillatory cloak and a family of localized states that connect uniform symmetric states ...

Clerc Gavilán, Marcel; Coulibaly, S.; Ferré Díaz, Michael A. (Elsevier, 2020)Despite the fact that female political participation has been steadily growing over time, women's representation in politics is substantially lower than their proportion in society. In this paper, we investigate the ...

Elías Moreno, Ricardo Gabriel (Universidad de ChilePrograma Cybertesis, 2009)En esta tesis se estudian los frentes y las estructuras localizadas en sistemas conformados por una gran cantidad de pequeños subsistemas idénticos acoplados entre sí, los cuales son descritos en términos de ecuaciones ...

Bordeu, I.; Clerc Gavilán, Marcel; Lefever, R.; Tlidi, M. (Elsevier, 2015)The stability of a circular localized spot with respect to azimuthal perturbations is studied in a prototype variational model, namely, a Swift-Hohenberg type equation. The conditions under which the circular shape of the ...

Alfaro Bittner, K.; Castillo-Pinto, C.; Clerc Gavilán, Marcel; González Cortés, Gregorio; Rojas, R.; Wilson, M. (American Physical Society, 2018)Spatially forced systems can exhibit coexistence and a rich interface dynamics between manipulable states. We show here how the propagation speed of a front into an unstable state can be modified through periodic space ...

Alfaro Bittner, K.; Castillo Pinto, C.; Clerc Gavilán, Marcel; González-Cortés, G.; Jara Schulz, G.; Rojas, R. G. (American Institute of Physics, 2020)Homogeneously driven dynamical systems exhibit multistability. Depending on the initial conditions, fronts present a rich dynamical behavior between equilibria. Qualitatively, this phenomenology is persistent under spatially ...
-
Clerc Gavilán, Marcel; Falcón Beas, Claudio; Tirapegui Zurbano, Enrique (AMERICAN PHYSICAL SOC, 2006-07)The effect of noise in a motionless front between a periodic spatial state and an homogeneous one is studied. Numerical simulations show that noise induces front propagation. From the subcritical Swift-Hohenberg equation ...

Residori, S.; Petrossian, A.; Nagaya, T.; Riera, C. S.; Clerc Gavilán, Marcel (ELSEVIER, 2004-12-01)We show that in a liquid-crystal-light-valve with optical feedback the Freedericksz transition displays a subcritical character. Experimentally, we determine the extension of the bistable region and we study the propagation ...
-
Clerc Gavilán, Marcel; Kowalczyk, Michal; Smyrnelis, Panayotis (World Scientific Publishing, 2020)In this paper, we describe domain walls appearing in a thin, nematic liquid crystal sample subject to an external field with intensity close to the Freedericksz transition threshold. Using the gradient theory of the phase ...
