Serguei Brazovskii 1, 2 x, France (2006) The family of molecular conductors TMTTF/TMTSF-X demonstrates almost all known electronic phases in parallel with a set of weak structural modifications of anion ordering and mysterious structureless transitions. Only in early 2000’s their nature became elucidated by discoveries of a huge anomaly in the dielectric permittivity and by the NMR evidences […]

M. R. Evans 1, 2, Satya N. Majumdar 3, R. K. P. Zia 4 Journal of Physics A 39 (2006) 4859-4873 We study a general mass transport model on an arbitrary graph consisting of $L$ nodes each carrying a continuous mass. The graph also has a set of directed links between pairs of nodes through which a stochastic portion of mass, chosen

We report

Satya N. Majumdar 2, David S. Dean 1 Journal of Statistical Mechanics: Theory and Experiment (2006) L07001 A simplified form of the quasispecies model of biological evolution is solved via a mapping onto a random flux model whose asymptotic behavior can be described in terms of a random walk. The statistics of the number of changes of the dominant species

G. Tellez 1, E. Trizac 2, 3 Journal of Statistical Mechanics: Theory and Experiment 1 (2006) P06018 The mathematical theory of integrable Painleve/Toda type systems sheds new light on the behavior of solutions to the Poisson-Boltzmann equation for the potential due to a long rod-like macroion. We investigate here the case of symmetric electrolytes together with that of 1:2 and

P. Visco 1, 2, A. Puglisi 1, A. Barrat 1, F. van Wijland 1, 3, E. Trizac 2 European Physical Journal B 51 (2006) 377 We investigate the behavior of energy fluctuations in several models of granular gases maintained in a non-equilibrium steady state. In the case of a gas heated from a boundary, the inhomogeneities of the system play a predominant role. Interpreting the total kinetic

Andrea Puglisi 1, Paolo Visco 1, 2, Emmanuel Trizac 2, Frederic van Wijland 1, 3 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 73 (2006) 021301 The dynamics of a tracer particle in a stationary driven granular gas is investigated. We show how to transform the linear Boltzmann equation describing the dynamics of the tracer into a master equation for a continuous Markov process.

Alejandro B. Kolton 1, Alberto Rosso 2, Thierry Giamarchi 1, Werner Krauth 3 Physical Review Letters 97 (2006) 057001 We study the steady-state low-temperature dynamics of an elastic line in a disordered medium below the depinning threshold. Analogously to the equilibrium dynamics, in the limit T->0, the steady state is dominated by a single configuration which is occupied with probability one. We develop
