Noise-Assisted Metastability: From Lévy Flights to Memristors, Quantum Escape, and Josephson-based Axion Searches
Claudio Guarcello, Alexander A. Dubkov, Davide Valenti +1
Many-body and complex systems, both classical and quantum, often exhibit slow, nonlinear relaxation toward stationary states due to the presence of metastable configurations and en…
Renormalization of Interacting Random Graph Models
Alessio Catanzaro, Diego Garlaschelli, Subodh P. Patil
Random graphs offer a useful mathematical representation of a variety of real world complex networks. Exponential random graphs, for example, are particularly suited towards genera…
Stochastic 0-dimensional Biogeochemical Flux Model: Effect of temperature fluctuations on the dynamics of the biogeochemical properties in a marine ecosystem
Paolo Lazzari, Roberto Grimaudo, Cosimo Solidoro +1
We present a new stochastic model, based on a 0-dimensional version of the well known biogeochemical flux model (BFM), which allows to take into account the temperature random fluc…
A Novel Exact Representation of Stationary Colored Gaussian Processes (Fractional Differential Approach)
Giulio Cottone, Mario Di Paola, Roberta Santoro
A novel representation of functions, called generalized Taylor form, is applied to the filtering of white noise processes. It is shown that every Gaussian colored noise can be expr…
Fractional Spectral Moments for Digital Simulation of Multivariate Wind Velocity Fields
Giulio Cottone, Mario Di Paola
In this paper, a method for the digital simulation of wind velocity fields by Fractional Spectral Moment function is proposed. It is shown that by constructing a digital filter who…
Scale-free relaxation of a wave packet in a quantum well with power-law tails
Salvatore Miccichè, Andreas Buchleitner, Fabrizio Lillo +3
We propose a setup for which a power-law decay is predicted to be observable for generic and realistic conditions. The system we study is very simple: A quantum wave packet initial…
