Boosting search by rare events
Andrea Montanari, Riccardo Zecchina
Randomized search algorithms for hard combinatorial problems exhibit a large variability of performances. We study the different types of rare events which occur in such out-of-equ…
Roughness distributions for 1/f^alpha signals
T. Antal, M. Droz, G. Gyorgyi +1
The probability density function (PDF) of the roughness, i.e., of the temporal variance, of 1/f^alpha noise signals is studied. Our starting point is the generalization of the mode…
Universality of coupled Potts models
Vl. S. Dotsenko, J. L. Jacobsen, X. S. Nguyen +1
We study systems of M Potts models coupled by their local energy density. Each model is taken to have a distinct number of states, and the permutational symmetry S_M present in the…
Nishimori point in random-bond Ising and Potts models in 2D
A. Honecker, J. L. Jacobsen, M. Picco +1
We study the universality class of the fixed points of the 2D random bond q-state Potts model by means of numerical transfer matrix methods. In particular, we determine the critica…
Statistics of charged solitons and formation of stripes
S Teber, B P Stojkovic, S A Brazovskii +1
The 2-fold degeneracy of the ground state of a quasi-one-dimensional system allows it to support topological excitations such as solitons. We study the combined effects of Coulomb…
On the definition of temperature in dense granular media
Vittoria Colizza, Alain Barrat, Vittorio Loreto
In this Letter we report the measurement of a pseudo-temperature for compacting granular media on the basis of the Fluctuation-Dissipation relations in the aging dynamics of a mode…
Equivalence of stationary state ensembles
H. J. Hilhorst, F. van Wijland
We show that the contact process in an ensemble with conserved total particle number, as simulated recently by Tome and de Oliveira [Phys. Rev. Lett. 86 (2001) 5463], is equivalent…
A Transfer Matrix for the Backbone Exponent of Two-Dimensional Percolation
J. L. Jacobsen, P. Zinn-Justin
Rephrasing the backbone of two-dimensional percolation as a monochromatic path crossing problem, we investigate the latter by a transfer matrix approach. Conformal invariance links…
On the velocity distributions of the one-dimensional inelastic gas
A. Barrat, T. Biben, Z. Racz +2
We consider the single-particle velocity distribution of a one-dimensional fluid of inelastic particles. Both the freely evolving (cooling) system and the non-equilibrium stationar…
Nature of the glassy phase of RNA secondary structure
F. Krzakala, M. Mezard, M. Mueller
We characterize the low temperature phase of a simple model for RNA secondary structures by determining the typical energy scale E(l) of excitations involving l bases. At zero temp…
Thermodynamic Properties of the Two-Dimensional Coulomb Gas in the Low-Density Limit
P. Kalinay, L. Samaj
The model under consideration is the two-dimensional Coulomb gas of charged hard disks with diameter . For the case of pointlike charges , the system is stable agai…
Randomly Driven Granular Fluids: collisional statistics and short scale structure
I. Pagonabarraga, E. Trizac, T. P. C. van Noije +1
We present a molecular dynamics and kinetic theory study of granular material, modeled by inelastic hard disks, fluidized by a random driving force. The focus is on collisional ave…
XY frustrated systems: continuous exponents in discontinuous phase transitions
M. Tissier, B. Delamotte, D. Mouhanna
XY frustrated magnets exhibit an unsual critical behavior: they display scaling laws accompanied by nonuniversal critical exponents and a negative anomalous dimension. This suggest…
Electrostatically swollen lamellar stacks and adiabatic pair potential of highly charged plate-like colloids in an electrolyte
Emmanuel Trizac
We show that describing the screened electrostatic interactions in a periodic stack of rigid parallel identical charged plate-like colloids within a local density functional theory…
Phase diagram and critical exponents of a Potts gauge glass
Jesper Lykke Jacobsen, Marco Picco
The two-dimensional q-state Potts model is subjected to a Z_q symmetric disorder that allows for the existence of a Nishimori line. At q=2, this model coincides with the +/- J rand…
Reply to: Comment on `Long-range electrostatic interactions between like-charged colloids: steric and confinement effects'
E. Trizac, J-L Raimbault
In his Comment (cond-mat/0104060) to [Phys. Rev. E 60, 6530 (1999)], Mateescu shows that while the effective interactions remain repulsive when the specific size of the micro-ions…
Dynamical Mean-Field Theory of Resonating Valence Bond Antiferromagnets
Antoine Georges, Rahul Siddharthan, Serge Florens
We propose a theory of the spin dynamics of frustrated quantum antiferromagnets, which is based on an effective action for a plaquette embedded in a self-consistent bath. This appr…
Phase Transitions in Non-extensive Spin Systems
Robert Botet, Marek Ploszajczak, Jorge A. Gonzalez
The spherical spin model with infinite-range ferromagnetic interactions is investigated analytically in the framework of non-extensive thermostatics generalizing the Boltzmann-Gibb…
Lattice Glass Models
Giulio Biroli, Marc Mezard
Motivated by the concept of geometrical frustration, we introduce a class of statistical mechanics lattice models for the glass transition. Monte Carlo simulations in three dimensi…
Density Correlations in the Two-Dimensional Coulomb Gas
L. Šamaj, B. Jancovici
We consider a two-dimensional Coulomb gas of positive and negative pointlike unit charges interacting via a logarithmic potential. The density (rather than the charge) correlation…
1/f Noise and Extreme Value Statistics
T. Antal, M. Droz, G. Gyorgyi +1
We study the finite-size scaling of the roughness of signals in systems displaying Gaussian 1/f power spectra. It is found that one of the extreme value distributions (Gumbel distr…

M. Grousson, G. Tarjus, P. Viot
We have investigated by Monte-Carlo simulation the phase diagram of a three-dimensional Ising model with nearest-neighbor ferromagnetic interactions and small, but long-range (Coul…
