Generalized Langevin equation with a three parameter Mittag-Leffler noise

Sandev, Trifce; Tomovski, Živorad; Dubbeldam, Johan L.A. - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 21, pp. 3627-3636

The relaxation functions for a given generalized Langevin equation in the presence of a three parameter Mittag-Leffler noise are studied analytically. The results are represented by three parameter Mittag-Leffler functions. Exact results for the velocity and displacement correlation functions of...

Excluded volume effect on entropy and clustering behaviors in supercooled liquids and glasses

Rah, Kyunil - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 1, pp. 27-39

We study the significant entropy changes in supercooling and glass transition by developing a two (H and L) state cluster model, where the H-state represents the clusters with the coordination number z being larger than the reference size zR and the L-state those with zzR, respectively. We...

Water behavior in the neighborhood of hydrophilic and hydrophobic membranes: Lessons from molecular dynamics simulations

Chara, Osvaldo; McCarthy, Andrés N.; Ferrara, C. Gastón; … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 21, pp. 4551-4559

The study of properties of water in the vicinity of surfaces poses a fascinating challenge. In this article we studied the behavior of water molecules in the neighborhood of membranes. We addressed the question of how these water molecules are influenced by the membranes’ hydrophilicity. Three...
