Journal ArticleDOI
Influence of noise on the synchronization of the stochastic Kuramoto model.
TL;DR: The Kuramoto model of globally coupled phase oscillators subject to Ornstein-Uhlenbeck and non-Gaussian colored noise is considered and the dependence of the threshold as well as the maximum degree of synchronization on the correlation time and the strength of the noise is studied.
Journal ArticleDOI
Noise properties of stochastic processes and entropy production.
TL;DR: The interplay of the properties of noise processes and the dissipative characteristic of the dynamical system in the steady state entropy production and flux is examined in a Fokker-Planck description of external Ornstein-Uhlenbeck noise and cross-correlated noise processes driving a dynamicals system.
Journal ArticleDOI
Solution of quantum Langevin equation: Approximations, theoretical and numerical aspects
TL;DR: This work extends the treatment to explore several systematic approximation schemes for the solutions of the Langevin equation for nonlinear potentials for a wide range of noise correlation, strength and temperature down to the vacuum limit.
Journal ArticleDOI
Colored multiplicative and additive non-Gaussian noise-driven dynamical system: Mean first passage time
TL;DR: In this article, the conspicuous dependence of mean first passage time (MFPT) on correlation time ( τ 2 ) of additive colored noise having fixed variance have been analyzed, and it has been observed that multiplicative colored non-Gaussian noise can induce resonant activation (RA).
Journal ArticleDOI
Approach to quantum Kramers' equation and barrier crossing dynamics.
TL;DR: The theory is a natural extension of the classical theory to quantum domain and provides a unified description of thermally activated processes and tunneling and is independent of path integral techniques.
