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…
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,…
Off-diagonal correlations of the Calogero-Sutherland model
G. E. Astrakharchik, D. M. Gangardt, Yu. E Lozovik +1
We study correlation functions of the Calogero-Sutherland model in the whole range of the interaction parameter. Using the replica method we obtain analytical expressions for the l…
Energy fluctuations in vibrated and driven granular gases
P. Visco, A. Puglisi, A. Barrat +2
We investigate the behavior of energy fluctuations in several models of granular gases maintained in a non-equilibrium steady state. In the case of a gas heated from a boundary, th…
Complex-temperature phase diagram of Potts and RSOS models
Jesper Lykke Jacobsen, Jean-Francois Richard, Jesus Salas
We study the phase diagram of Q-state Potts models, for Q=4 cos^2(PI/p) a Beraha number (p>2 integer), in the complex-temperature plane. The models are defined on L x N strips of t…
Unified Solution of the Expected Maximum of a Random Walk and the Discrete Flux to a Spherical Trap
Satya N. Majumdar, Alain Comtet, Robert M. Ziff
Two random-walk related problems which have been studied independently in the past, the expected maximum of a random walker in one dimension and the flux to a spherical trap of par…
Phase Transition in the Aldous-Shields Model of Growing Trees
David S. Dean, Satya N. Majumdar
We study analytically the late time statistics of the number of particles in a growing tree model introduced by Aldous and Shields. In this model, a cluster grows in continuous tim…
Canonical Analysis of Condensation in Factorised Steady State
M. R. Evans, Satya N. Majumdar, R. K. P. Zia
We study the phenomenon of real space condensation in the steady state of a class of mass transport models where the steady state factorises. The grand canonical ensemble may be us…
Strong clustering of non-interacting, passive sliders driven by a Kardar-Parisi-Zhang surface
Apoorva Nagar, Satya N. Majumdar, Mustansir Barma
We study the clustering of passive, non-interacting particles moving under the influence of a fluctuating field and random noise, in one dimension. The fluctuating field in our cas…
How long does it take to pull an ideal polymer into a small hole?
A. Y. Grosberg, S. Nechaev, M. Tamm +1
We present scaling estimates for characteristic times and of pulling ideal linear and randomly branched polymers of monomers into a small hole by a f…
Stationary state of a heated granular gas: fate of the usual H-functional
Ioana Bena, Francois Coppex, Michel Droz +3
We consider the characterization of the nonequilibrium stationary state of a randomly-driven granular gas in terms of an entropy-production based variational formulation. Enforcing…
Fluctuations of power injection in randomly driven granular gases
P. Visco, A. Puglisi, A. Barrat +2
We investigate the large deviation function pi(w) for the fluctuations of the power W(t)=w t, integrated over a time t, injected by a homogeneous random driving into a granular gas…
Fluctuations of internal energy flow in a vibrated granular gas
A. Puglisi, P. Visco, A. Barrat +2
The non-equilibrium fluctuations of power flux in a fluidized granular media have been recently measured in an experiment [Phys. Rev. Lett. 92, 164301, 2004], which was announced t…
Injected power and entropy flow in a heated granular gas
P. Visco, A. Puglisi, A. Barrat +2
Our interest goes to the power injected in a heated granular gas and to the possibility to interpret it in terms of entropy flow. We numerically determine the distribution of the i…
Spatial survival probability for one-dimensional fluctuating interfaces in the steady state
Satya N. Majumdar, Chandan Dasgupta
We report numerical and analytic results for the spatial survival probability for fluctuating one-dimensional interfaces with Edwards-Wilkinson or Kardar-Parisi-Zhang dynamics in t…
Zipf's law in Multifragmentation
Xavier Campi, Hubert Krivine
We discuss the meaning of Zipf's law in nuclear multifragmentation. We remark that Zipf's law is a consequence of a power law fragment size distribution with exponent .…
Asymptotic statistics of the n-sided planar Poisson-Voronoi cell. I. Exact results
Hendrik-Jan Hilhorst
We achieve a detailed understanding of the -sided planar Poisson-Voronoi cell in the limit of large . Let be the probability for a cell to have sides. We constru…
Spin waves in a one-dimensional spinor Bose gas
J. N. Fuchs, D. M. Gangardt, T. Keilmann +1
We study a one-dimensional (iso)spin 1/2 Bose gas with repulsive delta-function interaction by the Bethe Ansatz method and discuss the excitations above the polarized ground state.…
Precise Asymptotics for a Random Walker's Maximum
Alain Comtet, Satya N. Majumdar
We consider a discrete time random walk in one dimension. At each time step the walker jumps by a random distance, independent from step to step, drawn from an arbitrary symmetric…

Oksana Patsahan, Ihor Mryglod, Jean-Michel Caillol
The correlation functions of an ionic fluid with charge and size asymmetry are studied within the framework of the random phase approximation. The results obtained for the charge-c…
Casimir force between two ideal-conductor walls revisited
