In this work, we describe a simple Markovian algorithm to generate a typical sample path of colored noise described by an Ornstein–Uhlenbeck process. The algorithm works equally well to simulate a real or complex disorder potential with exponentially decaying covariance and higher correlation functions given by Wick's theorem. As an input, we only need independent Gaussian random numbers which can easily be generated by the well-known Box–Muller algorithm. Finally, we discuss an alternative…

The Entropy Production Distribution in Non-Markovian Thermal Baths

In this work we study the distribution function for the total entropy production of a Brownian particle embedded in a non-Markovian thermal bath. The problem is studied in the overdamped

Stochastic description of the light scattered by a polydisperse colloidal suspension: simulation and experiment.

It is proved from Doob's theorem that the electric field scattered by a polydisperse suspension can be accounted for by a linear combination of Ornstein-Uhlenbeck processes.

Approximate stationary solution and stochastic stability for a class of differential equations with parametric colored noise

This paper aims to study a class of differential equations with parametric Gaussian colored noise. We present the general framework to get the solvability conditions of the approximate stationary

Statistics of an autoregressive correlated random walk along a return path

A closed-form analytical solution is derived for the statistical outcome of a random walk along a return path. The random walk is generated from the cumulative sum of correlated samples in a

A unified view of hierarchy approach and formula of differentiation.

By manipulating the involved Ornstein-Uhlenbeck noise, this work proposes a unified algorithm that may reduce to the hierarchy approach or the formula of differentiation in different limits, and finds that the hierarchy approaches appears to be more efficient for numerical model studies.

A Spectral Model for RF Oscillators With Power-Law Phase Noise

It is shown that despite its lack of stationarity it is possible to derive a closed form expression for its effect on an oscillator PSD and that the oscillator output can be considered to be wide-sense stationary.

It is demonstrated that the AMVAR method performs better for very short data when compared to the multitaper method, and that coherence can still be detected in noisy bivariate time series data even if the individual power spectra fail to show any peaks.

Structures in Sound: Analysis of Classical Music Using the Information Length

The key idea is to envision music as the evolution of a non-equilibrium system and to construct probability distribution functions from musical instrument digital interface (MIDI) files of classical compositions to discuss a way to quantitatively discriminate between music and noise.

Coherent trapping in small quantum networks

We consider a three-node fully connected network (Delta network) showing that a coherent population trapping phenomenon occurs, generalizing results for the Lambda network known to support a dark



Fast and precise algorithm for computer simulation of stochastic differential equations.

An algorithm for integrating a set of stochastic differential equations driven by colored noise is presented and the limit of vanishingly small \ensuremath{\tau} can be safely taken, and the algorithm yields the corresponding white-noise quantities in a natural way.
