    • Normal modes and acoustic properties of an elastic solid with line defects 
      Lund Plantat, Fernando (Amer Phisical Soc, 2015)
      The normal modes of a continuum solid endowed with a random distribution of line defects that behave like elastic strings are described. These strings interact with elastic waves in the bulk, generating wave dispersion and ...
    • Normal Modes in Graphene for Different Geometries 
      Cáceres, Gabriel; González Cataldo, Felipe; Gutiérrez, Gonzalo (Institute of Physics Publishing, 2018)
      Using classical molecular dynamics, we study the time evolution of out-of-plane standing waves on a square and circular single-layer graphene membrane. We explore the first six normal modes, obtaining the oscillation ...

(Nature, 2021)
      Two serendipitously detected dust-obscured galaxies are reported at z = 6.7 and 7.4, with estimates that such galaxies provide an additional 10-25% contribution to the total star formation rate density at z > 6. Over ...
