Grand-canonical solution of semiflexible self-avoiding trails on the Bethe lattice

2017-02-24T10:00:00-05:00

Author(s): W. G. Dantas, Tiago J. Oliveira, Jürgen F. Stilck, and Thomas Prellberg
We consider a model of semiflexible interacting self-avoiding trails (sISATs) on a lattice, where the walks are constrained to visit each lattice edge at most once. Such models have been studied as an alternative to the self-attracting self-avoiding walks (SASAWs) to investigate the collapse transit…

Author(s): Vyacheslav V. Obukhovsky, Andrii M. Kutsyk, Viktoria V. Nikonova, and Oleksii O. Ilchenko
Mutual diffusion in multicomponent liquids is studied. It is taken into consideration that the influence of complex formation on the diffusion process may be substantial. The theory is applied to analyze mass transfer in an acetone-chloroform solution. The molecular complex concentration was obtaine…

Hydrodynamics in kinetically constrained lattice-gas models

2017-02-21T10:00:00-05:00

Author(s): Eial Teomy and Yair Shokef

This paper presents an approximation for the density-dependent diffusion coefficient that describes the behavior of kinetically constrained lattice-gas models. The authors show that non-negligible correlations appear in these models when the system is driven out of equilibrium. Such correlations also appear to be the reason for small discrepancies between approximations and numerical results for a broader group of models.
