    • Asenjo, Felipe A.; Muñoz, Víctor; Valdivia Hepp, Juan; Hada, Tohru (2009)
      The dispersion relation for circularly polarized electromagnetic waves propagating in the direction of an external magnetic field in a relativistic electron-positron plasma with arbitrary constant drift velocities is ...
    • Rogan Castillo, José; Ramírez, Max; Muñoz, Víctor; Valdivia Hepp, Juan; García, Griselda; Ramírez, Ricardo; Kiwi Tichauer, Miguel (2009)
      The determination of the spatial distributions that atoms adopt to form condensed matter is a problem of crucial importance, since most physical properties depend on the atomic arrangement. This is especially relevant for ...
    • Navarro, Roberto E.; Muñoz, Víctor; Araneda, Jaime A.; Viñas, Adolfo F.; Moya, Pablo S.; Valdivia Hepp, Juan (Blackwell Publishing Ltd, 2015)
      ©2015. American Geophysical Union. All Rights Reserved. Remote and in situ observations in the solar wind show that ion and electron velocity distributions persistently present deviations from thermal equilibrium. Ion ...
    • Villalobos, Jorge; Muñoz, Víctor; Rogan Castillo, José; Zarama, Roberto; Penagos, Juan Felipe; Toledo Cabrera, Benjamín; Valdivia Hepp, Juan (Amer Inst Physics, 2015)
      We propose a model of a bus traveling through a sequence of traffic lights, which is required to stop between the traffic signals to pick up passengers. A two dimensional model, of velocity and traveled time at each traffic ...
    • Pastén, Denisse; Muñoz, Víctor; Cisternas, Armando; Rogan Castillo, José; Valdivia Hepp, Juan (2011)
      Statistical and fractal properties of the spatial distribution of earthquakes in the central zone of Chile are studied. In particular, data are shown to behave according to the well-known Gutenberg-Richter law. The fractal ...
    • 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 ...
    • Muñoz Gutberlet, Pablo Rubén (Universidad de Chile, 2007)
      En esta tesis se estudiaron las ondas nolienales de Alfvén descritas por la ecuación nolineal de Srchródiger (DNLS) en presencia de un forzamiento externo. desde la perspectiva de los sistemas dinámicos. En la primera ...
    • López, Rodrigo A.; Muñoz, Víctor; Vinas, Adolfo F.; Valdivia Hepp, Juan (American Institute of Physics, 2015)
      We use a particle-in-cell simulation to study the propagation of localized structures in a magnetized electron-positron plasma with relativistic finite temperature. We use as initial condition for the simulation an envelope ...
    • Lammoglia, Nelson; Muñoz, Víctor; Rogan Castillo, José; Toledo Cabrera, Benjamín; Zarama, Roberto; Valdivia Hepp, Juan (2008)
      Data on wealth distributions in trading markets show a power law behavior x- (1+α) at the high end, where, in general, α is greater than 1 (Pareto's law). Models based on kinetic theory, where a set of interacting agents ...
    • Domínguez, Macarena; Nigro, Giuseppina; Muñoz, Víctor; Carbone, Vincenzo (American Institute of Physics Inc., 2018)
      An MHD shell model is used to describe the dissipative events that take place in magnetized plasmas. We analyze the activity of the time series of the magnetic energy dissipation rate obtained in the MHD shell model, which ...
    • Muñoz, Víctor; Cumsille, Sebastián; Günther Sapunar, Germán; Pizarro, Nancy; Vega, Andrés (Elsevier B.V., 2017)
      Tetra-tert-butyl-cis,cis-3,7-dihydroxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (I) and tetra-tert-butyl-cis,cis-3,7-dimethoxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (II) were ...
    • Domínguez, Macarena; Muñoz, Víctor; Valdivia Hepp, Juan (Blackwell Publishing Ltd, 2014)
      The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth's magnetosphere and the spatial distribution ...
    • Domínguez, Macarena; Muñoz, Víctor; Valdivia Hepp, Juan (2012)
      The propagation of circularly polarized electromagnetic waves along a constant background magnetic field in an electron-positron plasma is calculated by means of both a fluid and a kinetic theory treatment. In the fluid ...
    • Abe, Sumiyoshi; Pastén, Denisse; Muñoz, Víctor; Suzuki, Norikazu (2011)
      The scale-free and small-world properties are studied in detail for the complex earthquake networks constructed from the seismic data sets taken from California (USA), Japan, Iran and Chile. It is found that, in all these ...
