Long-Distance Transmission at Zero Dispersion: Exact Expressions for One-Time Statistical Properties
We study the transmission of a signal through a dispersionless fiber with in-line amplifiers. The nonlinearities of the fiber and the noise generated at each amplifier are taken into account. Exact analytical ...

Diffusion in a Disordered Line
There are many physical phenomena in which the diffusion process takes place. In most cases these phenomena are modelled by using particles moving in an homogeneous medium. The intrinsic heterogeneity of the m...

Random walk in dynamically disordered chains: Poisson white noise disorder
Exact solutions are given for a variety of models of random walks in a chain with time-dependent disorder. Dynamic disorder is modeled by white Poisson noise. Models with site-independent (global) and site-dep...

Master equation description of external poisson white noise in finite systems
We consider finite systems with random control parameters. A theory for a unified description of internal fluctuations and external noise is presented. Internal fluctuations are modeled by a one-step Markovian...

External Noise in Finite Systems
Stochastically driven systems exhibit a variety of interesting nonequilibrium effects. These have been recently reviewed by HORSTHEMKE and LEFEVER [1] and also addressed by other authors in this workshop. In t...
