    • Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test 

      Amigo, Nicolás [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Matemat Fis & Estadist, Chile]; Urbina, Felipe [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile] (Elsevier, 2020-11)
      The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ...
    • Collisions between amorphous carbon nanoparticles: phase transformations 

      Nietiadi, Maureen L.; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Gonzalez, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (EDP Sciences, 2020-09)
      Context. Collisions of nanoparticles (NPs) occur in dust clouds and protoplanetary disks.Aims. Sticking collisions lead to the growth of NPs, in contrast to bouncing or even fragmentation events and we aim to explore these ...
    • Towards an analytical description of active microswimmers in clean and in surfactant-covered drops 

      Sprenger, Alexander R.; Shaik, Vaseem A.; Ardekani, Arezoo M.; Lisicki, Maciej; Mathijssen, Arnold J. T. M.; Guzmán-Lastra, Francisca [‎Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Loewen, Hartmut; Menzel, Andreas M.; Daddi-Moussa-Ider, Abdallah (Chile. Universidad Mayor, 2020)
      Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow. Based on a far-field analytical model, ...
    • Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells 

      Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramírez, Max; Varas, Alejandro; Rogan, José (Chile. Universidad Mayor, 2020)
      The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
    • Correction to: Detecting social media users based on pedestrian networks and neighborhood attributes: an observational study 

      Masias, Victor H.; Hecking, Tobias; Crespo, Fernando [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Hoppe, H. Ulrich (Chile. Universidad Mayor, 2019)
      Following publication of the original article [1], the author reported that figure 5 numbered correction was not implemented during the production process. The corrected figure can be found below.
    • Detecting social media users based on pedestrian networks and neighborhood attributes: an observational study 

      Masias, Victor H.; Hecking, Tobias; Crespo, Fernando [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Hoppe, H. Ulrich (Chile. Universidad Mayor, 2019)
      This paper proposes a methodological approach to explore the ability to detect social media users based on pedestrian networks and neighborhood attributes. We propose the use of a detection function belonging to the Spatial ...
    • Coding closed and open quantum systems in MATLAB: applications in quantum optics and condensed matter 

      Norambuena, Ariel [Ctr Invest DAiTA LAB, Fac Estudios Interdisciplinarios, Univ Mayor, Chile]; Tancara, Diego; Coto, Raúl [Ctr Invest DAiTA LAB, Fac Estudios Interdisciplinarios, Univ Mayor, Chile] (IOP PUBLISHING LTD, 2020-07)
      We develop a package of numerical simulations implemented in MATLAB to solve complex many-body quantum systems. We focus on widely used examples that include the calculation of the magnetization dynamics for the closed and ...
    • Effect of phonons on the electron spin resonance absorption spectrum 

      Norambuena, Ariel [Ctr Invest DAiTA LAB, Fac Estudios Interdisciplinarios, Univ Mayor, Chile]; Jimenez, Alejandro; Becher, Christoph; Maze, Jerónimo R. (IOP Publishing Ltd., 2020-07)
      The unavoidable presence of vibrations in solid-state devices can drastically modify the expected electron spin resonance (ESR) absorption spectrum in magnetically active systems. In this work, we model the effect of phonons ...
