Lattice-gas modeling of adsorption on nanotube bundles at criticality

Pasinetti, P.M.; Riccardo, J.L.; Ramirez-Pastor, A.J. - In: Physica A: Statistical Mechanics and its Applications 355 (2005) 2, pp. 383-392

Adsorption thermodynamics of interacting particles adsorbed on nanotube bundles is studied through a lattice-gas model and Monte Carlo simulations. The adsorbent is modeled as one-dimensional channels of equivalent adsorption sites arranged in a triangular cross-sectional structure. Two kinds of...

Novel order parameter to describe the critical behavior of Ising spin glass models

Romá, F.; Nieto, F.; Ramirez-Pastor, A.J.; Vogel, E.E. - In: Physica A: Statistical Mechanics and its Applications 363 (2006) 2, pp. 327-333

A novel order parameter Φ for spin glasses is defined based on topological criteria and with a clear physical interpretation. Φ is first investigated for well known magnetic systems and then applied to the Edwards–Anderson ±J model on a square lattice, comparing its properties with the...
