Olivier Rivoire 1 Journal of Statistical Mechanics: Theory and Experiment 1 (2005) P04007 A method is introduced for studying large deviations in the context of statistical physics of disordered systems. The approach, based on an extension of the cavity method to atypical realizations of the quenched disorder, allows us to compute exponentially small probabilities (rate functions) over […]

Joel Chavas 1, Cyril Furtlehner 2, Marc Mezard 2, Riccardo Zecchina 3 Journal of Statistical Mechanics: Theory and Experiment P (2005) P11016 We discuss the implementation of two distributed solvers of the random K-SAT problem, based on some development of the recently introduced survey-propagation (SP) algorithm. The first solver, called the \’SP diffusion algorithm\’, diffuses as dynamical information the maximum bias over the

A. Braunstein 1, 2, M. Mezard 3, R. Zecchina 2 Random Structures and Algorithms 27 (2005) 201-226 We study the satisfiability of randomly generated formulas formed by $M$ clauses of exactly $K$ literals over $N$ Boolean variables. For a given value of $N$ the problem is known to be most difficult with $\\alpha=M/N$ close to the experimental threshold $\\alpha_c$ separating the region

G. Orso 1, G. V. Shlyapnikov 2, 3 Physical Review Letters 95 (2005) 260402 We calculate the superfluid transition temperature for a two-component 3D Fermi gas in a 1D tight optical lattice and discuss a dimensional crossover from the 3D to quasi-2D regime. For the geometry of finite size discs in the 1D lattice, we find that even for a

Mike Miller 1, Denis Ullmo 1, 2, Harold U. Baranger 1 Physical Review B 72 (2005) 045305 Despite considerable work on the energy-level and wavefunction statistics of disordered quantum systems, numerical studies of those statistics relevant for electron-electron interactions in mesoscopic systems have been lacking. We plug this gap by using a tight-binding model to study a wide variety of statistics for

Ya. Erukhimovich 1, 4 European Physical Journal E 17 (2005) 209-219 We investigate the statistical properties of a randomly branched 3–functional $N$–link polymer chain without excluded volume, whose one point is fixed at the distance $d$ from the impenetrable surface in a 3–dimensional space.
