  • Effects of aerogel-like disorder on the critical behavior of O(m)-vector models. Recent simulations and experimental evidence 
    Vasquez, C.; Paredes, R. (Condensed Matter Physics, 2006)
    We review recent results on the effect of a specific type of quenched disorder on well known O(m)-vector models in three dimensions: the XY model (3DXY, m = 2) and the Ising model (3DIS, m = 1). Evidence of changes of ...
  • Mochima theoretical physics spring school 
    Berche, B.; Donoso, A.; Paredes, R. (Condensed Matter Physics, 2006)
    The Mochima theoretical physics spring school on the Foundations of statistical and mesoscopic physics took place in Mochima, Edo. Sucre, Venezuela, between the 20th and 24th of June 2005. The Mochima biological station, ...
  • Nematic phase transitions in two-dimensional systems 
    Berche, B.; Paredes, R. (Condensed Matter Physics, 2005)
    Simulations of nematic-isotropic transition of liquid crystals in two dimensions are performed using an O(2) vector model characterized by non linear nearest neighbour spin interaction governed by the fourth Legendre polynomial ...
  • On the critical behaviour of two-dimensional liquid crystals 
    Fariñas-Sánchez, A.l.; Botet, R.; Berche, B.; Paredes, R. (Condensed Matter Physics, 2010)
    The Lebwohl-Lasher (LL) model is the traditional model used to describe the nematic-isotropic transition of real liquid crystals. In this paper, we develop a numerical study of the temperature behaviour and of finite-size ...
