    • Localized states in bistable pattern-forming systems 
      Bortolozzo, U.; Clerc Gavilán, Marcel; Falcón Beas, Claudio; Residori, S.; Rojas, R. (AMERICAN PHYSICAL SOC, 2006-06)
      We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously ...
    • New opportunities offered by Cubesats for space research in Latin America: The SUCHAI project case 
      Díaz, M. A.; Zagal Montealegre, Juan; Falcón Beas, Claudio; Stepanova, M.; Valdivia Hepp, Juan; Martínez Ledesma, M.; Díaz Peña, J.; Jaramillo, F. R.; Romanova, N.; Pacheco, E.; Milla, M.; Orchard Concha, Marcos; Silva, J.; Mena, F. P. (Elsevier, 2016)
      During the last decade, a very small-standardized satellite, the Cubesat, emerged as a low-cost fast-development tool for space and technology research. Although its genesis is related to education, the change in paradigm ...
    • Noise induced rolls propagation 
      Clerc Gavilán, Marcel; Falcón Beas, Claudio; Escaff, D.; Tirapegui Zurbano, Enrique (2007)
      Interfaces in two-dimensional systems exhibit unexpected complex dynamical behaviors. We present a robust effect of noise in two dimensional extended systems: the motion of a static front connecting a stripe pattern with ...
    • Noise-induced kink propagation in shallow granular layers 
      Jara Schulz, Gladys; Ferré Díaz, Michel; Falcón Beas, Claudio; Clerc Gavilán, Marcel (Elsevier, 2020)
      Out of equilibrium systems are characterized by exhibiting the coexistence of domains with complex spatiotemporal dynamics. Here, we investigate experimentally the noise-induced domain wall propagation on a one-dimensional ...
    • Non-propagating hydrodynamic solitons in a quasi-one dimensional free surface subject to vertical vibrations 
      Gordillo Zavaleta, Leonardo José (Universidad de Chile, 2012)
      Los solitones hidrodinámicos no propagativos son estructuras no lineales localizadas que aparecen en la superficie libre de un líquido cuasi-unidimensional que está sujeto a cierto tipo de inyección de energía, en particular, ...
    • Nonlinear and Nonhydrostatic Dynamics of Basin-Scale Waves in Stratified Rotating Lakes 
      Fuente Stranger, Alberto de la (Universidad de Chile, 2009)
      A escala diaria, el viento es el principal agente externo que entrega la energía suficiente a un lago estratificado para generar el movimiento del fluido y mezclar la columna de agua. Bajo este escenario, la dinámica ...
    • Order and density fluctuations in the vicinity of a granular solid-liquid-like phase transition 
      Castillo Bautista, Gustavo Emilio (Universidad de Chile, 2013)
      Esta tesis se dedica al estudio de las fluctuaciones de densidad, orden y de capilaridad en la vecindad de una transición de fase granular tipo sólido-líquido que ocurre en una monocapa granular vibrada de geometría ...
    • Statistics of injected power on a bouncing ball subjected to a randomly vibrating piston 
      García Cid, Alfredo; Gutiérrez, Pablo; Falcón Beas, Claudio; Aumaitre, Sébastien; Falcon, Eric (Amer Physical Soc, 2015)
      We present an experimental study on the statistical properties of the injected power needed to maintain an inelastic ball bouncing constantly on a randomly accelerating piston in the presence of gravity. We compute the ...
    • Symmetry-induced pinning-depinning transition of a subharmonic wave pattern 
      Garay, Jeremías; Ortega, Ignacio; Clerc Gavilán, Marcel; Falcón Beas, Claudio (AMER PHYSICAL SOC, 2012-03-05)
      The stationary to drifting transition of a subharmonicwave pattern is studied in the presence of inhomogeneities and drift forces as the pattern wavelength is comparable with the system size. We consider a pinning-depinning ...
    • Wave damping of a sloshing wave by an interacting turbulent vortex flow 
      Reyes Aspé, Francisco; Torrejón, Vicente; Falcón Beas, Claudio (American Physical Society, 2020)
      We report on the enhancement of the hydrodynamic damping of gravity waves at the surface of a fluid layer as they interact with a turbulent vortex flow in a sloshing experiment. Gravity surface waves are excited by oscillating ...
