Interplay between the glassy transition and granular superconductivity in organic materials

S. Senoussi, A. Tirbiyine, A. Ramzi +2

It is known that some (BEDT-TTF)2X layered organic superconductors undergo a glassy transition near 80 K. Our purpose is to exploit quenched disorder to get new insights on both th…

Reconstruction on trees and spin glass transition

Marc Mezard, Andrea Montanari

Consider an information source generating a symbol at the root of a tree network whose links correspond to noisy communication channels, and broadcasting it through the network. We…

Onsager-Manning-Oosawa condensation phenomenon and the effect of salt

Emmanuel Trizac, Gabriel Tellez

Making use of results pertaining to Painleve III type equations, we revisit the celebrated Onsager-Manning-Oosawa condensation phenomenon for charged stiff linear polymers, in the…

Topology Induced Coarsening in Language Games

A. Baronchelli, L. Dall'Asta, A. Barrat +1

We investigate how very large populations are able to reach a global consensus, out of local "microscopic" interaction rules, in the framework of a recently introduced class of mod…

The Dirac equation in Taub-NUT space

A. Comtet, P. A. Horvathy

Using chiral supersymmetry, we show that the massless Dirac equation in the Taub-NUT gravitational instanton field is exactly soluble and explain the arisal and the use of the dyna…

Gluon propagation inside a high-energy nucleus

Francois Gelis, Yacine Mehtar-Tani

We show that, in the light-cone gauge, it is possible to derive in a very simple way the solution of the classical Yang-Mills equations for the collision between a nucleus and a pr…

The antiferromagnetic transition for the square-lattice Potts model

Jesper Lykke Jacobsen, Hubert Saleur

We solve the antiferromagnetic transition for the Q-state Potts model (defined geometrically for Q generic) on the square lattice. The solution is based on a detailed analysis of t…

Quenched Averages for self-avoiding walks and polygons on deterministic fractals

Sumedha, Deepak Dhar

We study rooted self avoiding polygons and self avoiding walks on deterministic fractal lattices of finite ramification index. Different sites on such lattices are not equivalent,…

Dispersion and uncertainty in multislit matter wave diffraction

G. Glionna, A. H. Blin, B. Hiller +3

We show that single and multislit experiments involving matter waves may be constructed to assess correlations between the position and momentum of a single free particle. These co…
