On the self-assembly of net-like nanostructures in ferrofluids

Elkady, Ashraf S.; Iskakova, Larisa; Zubarev, Andrey - In: Physica A: Statistical Mechanics and its Applications 428 (2015) C, pp. 257-265

structural transformations and condensation in ferrofluids (FF). In this work, we study internal structural transformations in FF … formation of linear chains, Y-forks and net-like nanostructures. The results show that, in agreement with experiments, when the … united in individual linear chains. But, when these parameters exceed some threshold magnitude, the main particles population …

Periodic states, local effects and coexistence in the BML traffic jam model

Linesch, Nicholas J.; D’Souza, Raissa M. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 24, pp. 6170-6176

The Biham–Middleton–Levine (BML) model is simple lattice model of traffic flow, self-organization and jamming. Rather than a sharp phase transition between free-flow and jammed, it was recently shown that there is a region where stable intermediate states exist, with details dependent on the...

Analysis of transport phenomena with finite speed of perturbations propagation

Shnaid, Isaac - In: Physica A: Statistical Mechanics and its Applications 343 (2004) C, pp. 127-146

Known governing equations for transport phenomena predict infinite speed of perturbations propagation. From molecular point of view, infinite speed of perturbations propagation does not seem to be a reasonable physical assumption, because for instance in a gas, any perturbation propagates as a...

Time-dependent Onsager equations and perturbation propagation

Mostacci, Domiziano; Molinari, Vincenzo; Premuda, Margherita - In: Physica A: Statistical Mechanics and its Applications 316 (2002) 1, pp. 213-224

The diffusion of perturbations is investigated, beginning with Onsager-type equations for particle current and energy flow and conservation equations. This method takes into consideration the interplay of density and temperature, and the phenomena produced by this interplay—often neglected...

Irreversibility and entropy production in transport phenomena I

Suzuki, Masuo - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 11, pp. 1904-1916

The linear response framework was established a half-century ago, but no persuasive direct derivation of entropy production has been given in this scheme. This long-term puzzle has now been solved in the present paper. The irreversible part of the entropy production in the present theory is...

BML model on non-orientable surfaces

Cámpora, Daniel; de la Torre, Jaime; Vázquez, García; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 16, pp. 3290-3298

Two-dimensional Biham–Middleton–Levine traffic model on a N×N square lattice embedded on a Klein bottle and a projective plane is investigated by computer simulations. The behavior of the model with these boundary conditions is compared with the model under toroidal boundary conditions. Our...

Irreversibility and entropy production in transport phenomena, IV: Symmetry, integrated intermediate processes and separated variational principles for multi-currents

Suzuki, Masuo - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 19, pp. 4279-4287

The mechanism of entropy production in transport phenomena is discussed again by emphasizing the role of symmetry of non-equilibrium states and also by reformulating Einstein’s theory of Brownian motion to derive entropy production from it. This yields conceptual reviews of the previous papers...

Irreversibility and entropy production in transport phenomena, II: Statistical–mechanical theory on steady states including thermal disturbance and energy supply

Suzuki, Masuo - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 4, pp. 1074-1086

Some general aspects of nonlinear transport phenomena are discussed on the basis of two kinds of formulations obtained by extending Kubo’s perturbational scheme of the density matrix and Zubarev’s non-equilibrium statistical operator formulation. Both formulations are extended up to infinite...
