Interference of stochastic resonances: splitting of Kramers' rate.
نویسندگان
چکیده
We consider the escape of particles located in the middle well of a symmetric triple well potential driven sinusoidally by two forces such that the potential wells rock as in stochastic resonance and the height of the potential barrier oscillates symmetrically about a mean as in resonant activation. It has been shown that depending on their phase difference the application of these two synchronized signals may lead to a splitting of time averaged Kramers' escape rate and a preferential product distribution in a parallel chemical reaction in the steady state.

Achievable Secrecy Rate Regions of State Dependent Causal Cognitive Interference Channel
In this paper, the secrecy problem in the state dependent causal cognitive interference channel is studied. The channel state is non-causally known at the cognitive encoder. The message of the cognitive encoder must be kept secret from the primary receiver. We use a coding scheme which is a combination of compress-and-forward strategy with Marton coding, Gel’fand-Pinsker coding and Wyner’s wire...
متن کاملBackscattering in Silicon Microring Resonators: A Quantitative Analysis
Silicon microring resonators very often exhibit resonance splitting due to backscattering. This effect is hard to model in a quantitative and predictive way. This paper presents a behavioral circuit model for ring resonators that quantitatively explains the wide variations in resonance splitting observed in experiments. The model is based on an in-depth analysis of the contributions to backscat...
متن کاملEscape from a potential well with a randomly switching boundary
We consider diffusion in a potential well with a boundary that randomly switches between absorbing and reflecting and show how the switching boundary affects the classical escape theory. Using the theory of stochastic hybrid systems, we derive boundary value problems for the mean first passage time and splitting probability and find explicit solutions in terms of the spectral decomposition of t...
متن کاملGeneralization of the Classical Kramers Rate for Non-markovian Open Systems out of Equilibrium I Introduction: Metastability and Fluctuations Ii Generalizing the Langevin Approach Iii Our Fokker–planck Equation
We analyze the behavior of a Brownian particle moving in a double-well potential. The escape probability of this particle over the potential barrier from a metastable state toward another state is known as the Kramers problem. In this work we generalize Kramers' rate theory to the case of an environment always out of thermodynamic equilibrium reckoning with non-Markovian effects. We consider a ...
متن کاملTheoretical analysis of destabilization resonances in time-delayed stochastic second-order dynamical systems and some implications for human motor control.
A linear stochastic delay differential equation of second order is studied that can be regarded as a Kramers model with time delay. An analytical expression for the stationary probability density is derived in terms of a Gaussian distribution. In particular, the variance as a function of the time delay is computed analytically for several parameter regimes. Strikingly, in the parameter regime c...
