Diffusive transport in a one-dimensional disordered potential involving correlations

Cecile Monthus 1, 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 52 (1995) 2569-2573 This article deals with transport properties of one dimensional Brownian diffusion under the influence of a correlated quenched random force, distributed as a two-level Poisson process. We find in particular that large time scaling laws of the position of the Brownian particle

Diffractive orbits in quantum billiards

Nicolas Pavloff 1, Charles Schmit 1 Physical Review Letters 75 (1995) 61-64 We study diffractive effects in two dimensional polygonal billiards. We derive an analytical trace formula accounting for the role of non-classical diffractive orbits in the quantum spectrum. As an illustration the method is applied to a triangular billiard. 1.

Comment on \’ Thermodynamics of a One- Dimensional Ideal Gas with fractional Exclusion Statistics \’

Alain Dasnieres De Veigy 1, Stéphane Ouvry 1 Physical Review Letters 75 (1995) 352 In a recent letter -Phys. Rev. Lett. 73, 3331 (1995)-, the conclusion was reached that, in the one-dimensional Calogero model, only the second virial coefficient is affected by the statistical parameter $\\alpha$, where $\\alpha$ is related to the coupling constant $\\kappa/ x_{ij}^2$ of the Calogero

Calogero Models for Distinguishable Particles

Cyril Furtlehner 1, Stephane Ouvry 1 Modern Physics Letters B 9 (1995) 503-509 Motivated by topological bidimensional quantum models for distinguishable particles, and by Haldane\’s definition of mutual statistics for different species of particles, we propose a new class of one-dimensional $1/r_{ij}^2$ Calogero model with coupling constants $g_{ij}$ depending on the labels of the particles. We solve the groundstate
