A "Little Big Bang" Scenario of Multifragmentation
X. Campi, H. Krivine, E. Plagnol +1
We suggest a multifragmentation scenario in which fragments are produced at an early, high temperature and high density, stage of the reaction. In this scenario, self-bound cluster…
A molecular dynamics "Maxwell Demon" experiment for granular mixtures
A. Barrat, E. Trizac
We report a series of molecular dynamics simulations and investigate the possibility to separate a granular mixture of inelastic hard spheres by vigorously shaking it in a box made…
Statistical Field Theory for Simple fluids : Mean Field and Gaussian Approximations
J. - M. Caillol
We present an exact field theoretical representation of the statistical mechanics of simple classical liquids with short-ranged pairwise additive interactions. The action of the fi…
Exact Potts Model Partition Functions for Strips of the Triangular Lattice
Shu-Chiuan Chang, Jesper Lykke Jacobsen, Jesús Salas +1
We present exact calculations of the Potts model partition function Z(G,q,v) for arbitrary q and temperature-like variable v on n-vertex strip graphs G of the triangular lattice fo…
Tree Networks with Causal Structure
P. Bialas, Z. Burda, J. Jurkiewicz +1
Geometry of networks endowed with a causal structure is discussed using the conventional framework of equilibrium statistical mechanics. The popular growing network models appear a…
Metastable configurations on the Bethe lattice
A. Pagnani, G. Parisi, M. Ratieville
We present a general analytic method to compute the number of metastable configurations as a function of the energy for a system of interacting Ising spins on the Bethe lattice. Ou…
Extreme events driven glassy behaviour in granular media
G. D'Anna, P. Mayor, G. Gremaud +2
Motivated by recent experiments on the approach to jamming of a weakly forced granular medium using an immersed torsion oscillator [Nature 413 (2001) 407], we propose a simple mode…
Dynamics of ballistic annihilation
Jaroslaw Piasecki, Emmanuel Trizac, Michel Droz
The problem of ballistically controlled annihilation is revisited for general initial velocity distributions and arbitrary dimension. An analytical derivation of the hierarchy equa…
Incomplete ordering of the voter model on small-world networks
Claudio Castellano, Daniele Vilone, Alessandro Vespignani
We investigate how the topology of small-world networks affects the dynamics of the voter model for opinion formation. We show that, contrary to what occurs on regular topologies w…
Some exact results for Boltzmann's annihilation dynamics
Francois Coppex, Michel Droz, Jaroslaw Piasecki +2
The problem of ballistic annihilation for a spatially homogeneous system is revisited within Boltzmann's kinetic theory in two and three dimensions. Exact analytical results are de…
Critical load and congestion instabilities in scale-free networks
Y. Moreno, R. Pastor-Satorras, A. Vazquez +1
We study the tolerance to congestion failures in communication networks with scale-free topology. The traffic load carried by each damaged element in the network must be partly or…
Multi-species pair annihilation reactions
Olivier Deloubriere, Henk Hilhorst, Uwe C. Tauber
We consider diffusion-limited reactions A_i + A_j -> 0 (1 <= i < j <= q) in d space dimensions. For q > 2 and d >= 2 we argue that the asymptotic density decay for such mutual anni…
On the Reactions A+A+...+A->0 at a One-Dimensional Periodic Lattice of Catalytic Centers: Exact Solution
A. A. Naidenov, S. K. Nechaev
The kinetics of the diffusion-controlled chemical reactions A+A+...+A->0 that occur at catalytic centers periodically arranged along a straight line is considered. Modes of the beh…
Conformal field theory of the Flory model of polymer melting
Jesper Lykke Jacobsen, Jane' Kondev
We study the scaling limit of a fully packed loop model in two dimensions, where the loops are endowed with a bending rigidity. The scaling limit is described by a three-parameter…
Universality class of nonequilibrium phase transitions with infinitely many-absorbing-states
F. van Wijland
We consider systems whose steady-states exhibit a nonequilibrium phase transition from an active state to one -among an infinite number- absorbing state, as some control parameter…
Topology and correlations in structured scale-free networks
Alexei Vazquez, Marian Boguna, Yamir Moreno +2
We study a recently introduced class of scale-free networks showing a high clustering coefficient and non-trivial connectivity correlations. We find that the connectivity probabili…
The Local Time Distribution of a Particle Diffusing on a Graph
Alain Comtet, Jean Desbois, Satya N. Majumdar
We study the local time distribution of a Brownian particle diffusing along the links on a graph. In particular, we derive an analytic expression of its Laplace transform in terms…
Exact Asymptotic Results for Persistence in the Sinai Model with Arbitrary Drift
Satya N. Majumdar, Alain Comtet
We obtain exact asymptotic results for the disorder averaged persistence of a Brownian particle moving in a biased Sinai landscape. We employ a new method that maps the problem of…
Absence of epidemic threshold in scale-free networks with connectivity correlations
Marian Boguna, Romualdo Pastor-Satorras, Alessandro Vespignani
Random scale-free networks have the peculiar property of being prone to the spreading of infections. Here we provide an exact result showing that a scale-free connectivity distribu…
Determination of the friction coefficient of a Brownian particle by molecular-dynamics simulation
F. Ould Kaddour, D. Levesque
By using the Kirkwood formula, the friction coefficient of a solvated Brownian particle is determined from the integration on time of the autocorrelation function of the force that…
Molecular dynamics simulations of vibrated granular gases
Alain Barrat, Emmanuel Trizac
We present molecular dynamics simulations of mono- or bidisperse inelastic granular gases driven by vibrating walls, in two dimensions (without gravity). Because of the energy inje…
Short period attractors and non-ergodic behavior in the deterministic fixed energy sandpile model
Franco Bagnoli, Fabio Cecconi, Alessandro Flammini +1
We study the asymptotic behaviour of the Bak, Tang, Wiesenfeld sandpile automata as a closed system with fixed energy. We explore the full range of energies characterizing the acti…
Uncorrelated Random Networks
Z. Burda, A. Krzywicki
We define a statistical ensemble of non-degenerate graphs, i.e. graphs without multiple- and self-connections between nodes. The node degree distribution is arbitrary, but the node…
Statistical Physics of RNA-folding
M. Mueller
We discuss the physics of RNA as described by its secondary structure. We examine the static properties of a homogeneous RNA-model that includes pairing and base stacking energies…
