    • Non-smooth transitions in a simple city traffic model analyzed through supertracks 
      Toledo Cabrera, Benjamín; San Juan López, María Angélica; Muñoz Gálvez, Víctor; Rogan Castillo, José; Valdivia Hepp, Juan (Elsevier, 2013)
      We explore the nontrivial behavior of a particular city traffic model due to its minimalistic representation of basic city traffic dynamics. The chaotic behavior is studied through the supertrack functions, an approach ...
    • Non-universal critical exponents in earthquake complex networks 
      Pastén, Denisse; Torres, Felipe; Toledo Cabrera, Benjamín; Muñoz, Víctor; Rogan Castillo, José; Valdivia, Juan (Elsevier B.V., 2018)
      The problem of universality of critical exponents in complex networks is studied based on networks built from seismic data sets. Using two data sets corresponding to Chilean seismicity (northern zone, including the 2014 ...
    • Optimal control in a noisy system 
      Asenjo, F.; Toledo Cabrera, Benjamín; Muñoz Gálvez, Víctor; Rogan Castillo, José; Valdivia Hepp, Juan (AMER INST PHYSICS, 2008-07-21)
      We describe a simple method to control a known unstable periodic orbit UPO in the presence of noise. The strategy is based on regarding the control method as an optimization problem, which allows us to calculate a ...
    • Regular transport dynamics produce chaotic travel times 
      Villalobos, Jorge; Muñoz Gálvez, Víctor; Rogan Castillo, José; Zarama, Roberto; Johnson, Neil F.; Toledo Cabrera, Benjamín; Valdivia Hepp, Juan (American Physical Society, 2014)
      In the hope of making passenger travel times shorter and more reliable, many cities are introducing dedicated bus lanes (e.g., Bogota, London, Miami). Herewe showthat chaotic travel times are actually a natural consequence of ...
    • Solitonic elliptical solutions in the classical XY-model 
      Ferrer, Rodrigo; Rogan Castillo, José; Davis, Sergio; Gutiérrez Gallardo, Gonzalo (ELSEVIER, 2006-10-01)
      The solitonic-like solutions predicted by the continuum semi-classical two-dimensional XY-model are investigated using canonical Monte Carlo simulation. In particular, we verify the existence of kink states, and study their ...
    • A Strategy to Find Minimal Energy Nanocluster Structures 
      Rogan Castillo, José; Varas, Alejandro; Valdivia Hepp, Juan; Kiwi Tichauer, Miguel (Wiley Periodicals, 2013)
    • Structural and vibrational properties of amorphous GeO2: a molecular dynamics study 
      Peralta, Joaquín; Gutiérrez Gallardo, Gonzalo; Rogan Castillo, José (IOP PUBLISHING LTD, 2008-04-09)
      We studied the structural and dynamical properties of amorphous germanium oxide (GeO2) by means of the molecular dynamics technique. The simulations were done in the microcanonical ensemble, with a system at density of ...
    • Structural, electronic, and magnetic properties of FexCoyPdz (x + y + z £ 7) clusters: a density functional ... 
      Varas, Alejandro; Aguilera Granja, F.; Rogan Castillo, José; Kiwi Tichauer, Miguel (2016)
      Transition metal alloy nanoparticles are of interest both theoretically and experimentally, particularly due to their potential technological applications, and to their novel structural and magnetic properties in the ...
    • The magnetosphere as a complex system 
      Valdivia Hepp, Juan; Rogan Castillo, José; Muñoz, Victor; Toledo Cabrera, Benjamín; Stepanova, Marina (2013)
      The magnetosphere is a multi-scale spatio-temporal complex dynamical system. In this context, we have analyzed the multifractal behavior of the AL index, as a proxy for an energy dissipation rate, using discrete wavelet ...
