Exact numerical simulation of the Ornstein-Uhlenbeck process and its integral

DT Gillespie - Physical review E, 1996 - APS
A numerical simulation algorithm that is exact for any time step Δt> 0 is derived for the
Ornstein-Uhlenbeck process X (t) and its time integral Y (t). The algorithm allows one to …

Spectral methods in chemistry and physics

B Shizgal - Scientific Computation. Springer, 2015 - Springer
Spectral and pseudospectral methods have become increasingly popular as higher order
methods for the solution of partial differential and integral equations (Azaïez et al. 2013). A …

Fokker-Planck perspective on stochastic delay systems: Exact solutions and data analysis of biological systems

TD Frank, PJ Beek, R Friedrich - Physical Review E, 2003 - APS
Stochastic delay systems with additive noise are examined from the perspective of Fokker-
Planck equations. For a linear system, the exact stationary probability density is derived by …

Tracer particle in a confined correlated medium: an adiabatic elimination method

D Venturelli, M Gross - Journal of Statistical Mechanics: Theory …, 2022 - iopscience.iop.org
We present a simple and systematic procedure to determine the effective dynamics of a
Brownian particle coupled to a rapidly fluctuating correlated medium, modeled as a scalar …

Stochastic resonance in a linear system: An exact solution

H Calisto, F Mora, E Tirapegui - Physical Review E—Statistical, Nonlinear, and …, 2006 - APS
Multistable systems can exhibit stochastic resonance which is characterized by the
amplification of small periodic signals by additive noise. Here we consider a nonmultistable …

Dynamics and steady states of a tracer particle in a confined critical fluid

M Gross - Journal of Statistical Mechanics: Theory and …, 2021 - iopscience.iop.org
The dynamics and the steady states of a point-like tracer particle immersed in a confined
critical fluid are studied. The fluid is modeled field-theoretically in terms of an order …

Coarse-scale representations and smoothed Wigner transforms

AG Athanassoulis, NJ Mauser, T Paul - Journal de mathematiques pures et …, 2009 - Elsevier
Smoothed Wigner transforms have been used in signal processing, as a regularized version
of the Wigner transform, and have been proposed as an alternative to it in the …

Pseudospectral solution of the Fokker–Planck equation with equilibrium bistable states: the eigenvalue spectrum and the approach to equilibrium

BD Shizgal - Journal of Statistical Physics, 2016 - Springer
Abstract The Fokker–Planck equation with a constant diffusion coefficient and a particular
polynomial drift coefficient can exhibit a bistable equilibrium distribution. Such model …

Higher-order Fokker–Planck type equations and the first-passage times in bounded domains

SI Serdyukov - Physica A: Statistical Mechanics and its Applications, 2025 - Elsevier
We consider one-dimensional anomalous diffusion of free Brownian particle. A time-
dependent probability density function for search process was obtained based on …

[HTML][HTML] Non-Markovian effects on the Brownian motion of a free particle

AO Bolivar - Physica A: Statistical Mechanics and its Applications, 2011 - Elsevier
Non-Markovian effects on the Brownian movement of a free particle in the presence as well
as in the absence of inertial force are investigated under the framework of generalized …
