      Cuevas-Maraver, Jesús; Sánchez-Rey, Bernardo (2007)
      Interstitials and vacancies, in one-dimensional lattices, are point defects that can be modelled by means of kinks or antikinks in a discrete Frenkel-Kontorova model, with a sine-Gordon on-site potential. The properties ...

      Effect of breather existence on reconstructive transformations in mica muscovite  [Presentation]

      Archilla, Juan F. R.; Cuevas-Maraver, Jesús; Romero Romero, Francisco (2008)
      Reconstructive transformations of layered silicates as mica muscovite take place at much lower temperatures than expected. A possible explanation is the existence of breathers within the potassium layer. Numerical analysis ...
