Edwards' measures: a thermodynamic construction for dense granular media and glasses
Alain Barrat, Jorge Kurchan, Vittorio Loreto +1
We present numerical support for the hypothesis that macroscopic observables of dense granular media can be evaluated from averages over typical blocked configurations: we construc…
Transfer Matrices and Partition-Function Zeros for Antiferromagnetic Potts Models II. Extended Results for Square-Lattice Chromatic Polynomial
Jesper Lykke Jacobsen, Jesús Salas
We study the chromatic polynomials for m \times n square-lattice strips, of width 9 <= m <= 13 (with periodic boundary conditions) and arbitrary length n (with free boundary condit…
Surface Tension of a Metal-Electrolyte Boundary: Exactly Solvable Model
L. Šamaj, B. Jancovici
An ideal conductor electrode in contact with a semi-infinite two-dimensional two-component plasma in an external potential is considered. The model is mapped onto an integrable sin…
Pressure and Stress Tensor in a Yukawa Fluid
B. Jancovici
Systems of particles interacting through a screened Coulomb potential of the Debye-Yukawa form are considered. The pressure is obtained from the stress tensor of the field correspo…
Reply to ``Comment on `Critical behavior of a two-species reaction-diffusion problem' ''
J. E. de Freitas, L. S. Lucena, L. R. da Silva +1
Our recent Monte Carlo results [Phys. Rev. E 61 (2000) 6330] for the one-dimensional reaction-diffusion process A+B->2B and B->A lead to the correlation length exponent estimate nu…
Phase diagram of an Ising model with long-range frustrating interactions: a theoretical analysis
M. Grousson, G. Tarjus, P. Viot
We present a theoretical study of the phase diagram of a frustrated Ising model with nearest-neighbor ferromagnetic interactions and long-range (Coulombic) antiferromagnetic intera…
Free cooling and inelastic collapse of granular gases in high dimensions
E. Trizac, A. Barrat
The connection between granular gases and sticky gases has recently been considered, leading to the conjecture that inelastic collapse is avoided for space dimensions higher than 4…
Edwards measures for powders and glasses
A. Barrat, J. Kurchan, V. Loreto +1
Can one construct a thermodynamics for compact, slowly moving powders and grains? A few years ago, Edwards proposed a possible step in this direction, raising the fascinating persp…
Statistical properties of the 2D attached Rouse chain
Olivier Benichou, Jean Desbois
We study various dynamical properties (winding angles, areas) of a set of harmonically bound Brownian particles (monomers), one endpoint of this chain being kept fixed at the origi…
Windings of the 2D free Rouse chain
Olivier Benichou, Jean Desbois
We study long time dynamical properties of a chain of harmonically bound Brownian particles. This chain is allowed to wander everywhere in the plane. We show that the scaling varia…
Multifractality in uniform hyperbolic lattices and in quasi-classical Liouville field theory
A. Comtet, S. Nechaev, R. Voituriez
We introduce a deterministic model defined on a two dimensional hyperbolic lattice. This model provides an example of a non random system whose multifractal behaviour has a number…
A universality class in Markovian persistence
Olivier Deloubriere
We consider the class of Markovian processes defined by the equation $\dd x /\dd t = -βx + \sum_k z_k δ(t-t_k)$. Such processes are encountered in systems (like coalescing systems)…
Universal free energy correction for the two-dimensional one-component plasma
Bernard Jancovici, Emmanuel Trizac
The universal finite-size correction to the free energy of a two-dimensional Coulomb system is checked in the special case of a one-component plasma on a sphere. The correction is…
Universal features of the order-parameter fluctuations : reversible and irreversible aggregation
R. Botet, M. Ploszajczak
We discuss the universal scaling laws of order parameter fluctuations in any system in which the second-order critical behaviour can be identified. These scaling laws can be derive…
Generalized model for dynamic percolation
O. Benichou, J. Klafter, M. Moreau +1
We study the dynamics of a carrier, which performs a biased motion under the influence of an external field E, in an environment which is modeled by dynamic percolation and created…
From second to first order transitions in a disordered quantum magnet
Leticia F. Cugliandolo, Daniel R. Grempel, Constantino A. da Silva Santos
We study the spin-glass transition in a disordered quantum model. There is a region in the phase diagram where quantum effects are small and the phase transition is second order, a…
Exact Meander Asymptotics: a Numerical Check
Philippe Di Francesco, Emmanuel Guitter, Jesper Lykke Jacobsen
This note addresses the meander enumeration problem: "Count all topologically inequivalent configurations of a closed planar non self-intersecting curve crossing a line through a g…
Multifractality of entangled random walks and non-uniform hyperbolic spaces
R. Voituriez, S. Nechaev
Multifractal properties of the distribution of topological invariants for a model of trajectories randomly entangled with a nonsymmetric lattice of obstacles are investigated. Usin…
