We experimentally study the statistical properties of the energy fluxes in two systems whose components are kept at different temperatures. The first system under consideration is an electric circuit which is composed by two resistances, kept at diff

We study the dynamics of an asymmetric intruder in a glass-former model. At equilibrium, the intruder diffuses with average zero velocity. After an abrupt quench to T deeply under the mode-coupling temperature, a net average drift is observed, steady

We study the finite size fluctuations at the depinning transition for a one-dimensional elastic interface of size $L$ displacing in a disordered medium of transverse size $M=k L^\zeta$ with periodic boundary conditions, where $\zeta$ is the depinning

Here, we introduce a statistical approach derived from dynamics, for the study of the geophysical fluid dynamics phenomena characterized by a weak interaction among the variables of interest and the rest of the system. The approach is reminiscent of

Noise-induced resonance-like phenomena in InP crystals embedded in fluctuating electric fields

Autor: Bernardo Spagnolo, Nicola Pizzolato, D. Persano Adorno

Publikováno v: Journal of Statistical Mechanics: Theory and Experiment. 2016:054021

We explore and discuss the complex electron dynamics inside a low-doped n-type InP bulk embedded in a sub-THz electric field, fluctuating for the superimposition of an external source of Gaussian correlated noise. The results presented in this study

We study how the Einstein relation between spontaneous fluctuations and the response to an external perturbation holds in the absence of currents, for the comb model and the elastic single-file, which are examples of systems with subdiffusive transpo

Anomalous diffusion on finite intervals

Autor: Bartłomiej Dybiec

We study the properties of anomalous diffusion on finite intervals. The process studied due to the presence of trapping events and long jumps is described by a double-fractional (time and space) Fokker–Planck equation. The properties of the overall

Monte Carlo study of diffusion noise reduction in GaAs operating under periodic conditions

Autor: PERSANO ADORNO, Dominique, PIZZOLATO, Nicola, SPAGNOLO, Bernardo

The effects of an external correlated source of noise on the intrinsic carrier noise in a low-doped GaAs bulk, operating under periodic conditions, are investigated. Numerical residts confirm that the dynamical response of electrons driven by a high-

Noise influence on electron dynamics in semiconductors driven by a periodic electric field

Autor: Adorno, D. Persano, Pizzolato, N., Spagnolo, B.

Studies about the constructive aspects of noise and fluctuations in different non-linear systems have shown that the addition of external noise to systems with an intrinsic noise may result in a less noisy response. Recently, the possibility to reduc

In this paper using a projection approach and defining the adjoint-Lie time evolution of differential operators, that generalizes the ordinary time evolution of functions, we obtain a Fokker-Planck equation for the distribution function of a part of
