Stephane Ouvry 1 Journal of Statistical Mechanics: Theory and Experiment 1 (2005) P09004 A review of the random magnetic impurity model, introduced in the context of the integer Quantum Hall effect, is presented. It models an electron moving in a plane and coupled to random Aharonov-Bohm vortices carrying a fraction of the quantum of flux. Recent results […]

Christophe Texier 1, 2, Gilles Montambaux 2 Journal of Physics A 38 (2005) 3455-3471 We consider the weak localization correction to the conductance of a ring connected to a network. We analyze the harmonics content of the Al\’tshuler-Aronov-Spivak (AAS) oscillations and we show that the presence of wires connected to the ring is responsible for a behaviour different from the

P. Di Francesco 1, Paul Zinn-Justin 2 Journal of Physics A 38 (2005) L815-L822 We prove higher rank analogues of the Razumov–Stroganov sum rule for the groundstate of the O(1) loop model on a semi-infinite cylinder: we show that a weighted sum of components of the groundstate of the A_{k-1} IRF model yields integers that generalize the numbers of

N. Bilas 1, N. Pavloff 1 Physical Review Letters 95 (2005) 130403 We consider the propagation of a dark soliton in a quasi 1D Bose-Einstein condensate in presence of a random potential. This configuration involves nonlinear effects and disorder, and we argue that, contrarily to the study of stationary transmission coefficients through a nonlinear disordered slab, it is a

Alain Comtet 1, 2, Satya N. Majumdar 1 Journal of Statistical Mechanics: Theory and Experiment 06 (2005) P06013 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 density function. We show that the expected positive maximum E[M_n] of

Satya N. Majumdar 1, Dibyendu Das 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 71 (2005) 036129 We study the persistence properties in a simple model of two coupled interfaces characterized by heights h_1 and h_2 respectively, each growing over a d-dimensional substrate. The first interface evolves independently of the second and can correspond to any generic

Apoorva Nagar 1, Mustansir Barma 1, Satya N. Majumdar 2 Physical Review Letters 94 (2005) 240601 We study the clustering properties of particles sliding downwards on a fluctuating surface evolving through the Kardar-Parisi-Zhang equation, a problem equivalent to passive scalars driven by a Burgers fluid. Monte Carlo simulations on a discrete version of the problem in one dimension reveal that particles
