      Prados Montaño, Antonio; Trizac, E. (American Physical Society, 2014-05-14)
      While memory effects have been reported for dense enough disordered systems such as glasses, we show here by a combination of analytical and simulation techniques that they are also intrinsic to the dynamics of dilute ...

      Large Mpemba-like effect in a gas of inelastic rough hard spheres  [Article]

      Torrente, Aurora; López Castaño, Miguel A.; Lasanta, Antonio; Vega Reyes, Francisco; Prados Montaño, Antonio; Santos, Andrés (American Physical Society, 2019)
      We report the emergence of a giant Mpemba effect in the uniformly heated gas of inelastic rough hard spheres: The initially hotter sample may cool sooner than the colder one, even when the initial temperatures differ by ...

      Linear hydrodynamics for driven granular gases  [Article]

      García de Soria Lucena, María Isabel; Maynar Blanco, Pablo (American Physical Society, 2013)
      We study the dynamics of a granular gas heated by a stochastic thermostat. From a Boltzmann description, we derive the hydrodynamic equations for small perturbations around the stationary state that is reached in the long ...

      Linear response of vibrated granular systems to sudden changes in the vibration intensity  [Article]

      Brey Abalo, José Javier; Prados Montaño, Antonio (American Physical Society, 2001)
      The short-term memory effects recently observed in vibration-induced compaction of granular materials are studied. It is shown that they can be explained by means of quite plausible hypothesis about the mesoscopic description ...

      Liquid crystal behavior of the Kihara fluid  [Article]

      Cuetos, Alejandro; Martínez-Haya, Bruno; Lago, S.; Rull Fernández, Luis Felipe (American Physical Society, 2003)
      The liquid crystal phases of the Kihara fluid have been studied in computer simulations. The work focuses on the isotropic–nematic–smectic-A triple point region, especially relevant for the understanding of the properties and ...
