A method for the reconstruction of the amplitudes and phases […]

J. Lukic 1, E. Marinari 2, O. C. Martin 3 Europhysics Letters (EPL) 73 (2006) 779-785 The ground state and low T behavior of two-dimensional spin systems with discrete binary couplings are subtle but can be analyzed using exact computations of finite volume partition functions. We first apply this approach to Villain’s fully frustrated model, unveiling an unexpected finite size scaling

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

In the case of a gas heated from a boundary, the inhomogeneities of the system play a predominant role. Interpreting the total kinetic
