For optimally selected values of the additive noise intensity stochastic resonance is observed, which is manifested by a maximal coherence between the dynamics of the mean field and the periodic input. Numerical simulations of the signal-to-noise ratio and theoretical results from an effective two state model are in good quantitative agreement.}, language = {en} } @article{LandaZaikinSchimanskyGeier2001, author = {Landa, Polina S. and Zaikin, Alexei A. and Schimansky-Geier, Lutz}, title = {Effect of the potential shape and of a Brownian particle mass on noise-induced transport}, year = {2001}, language = {en} } @article{ZaikinGarciaOjalvoSchimanskyGeieretal.2002, author = {Zaikin, Alexei A. and Garc{\´i}a-Ojalvo, Jordi and Schimansky-Geier, Lutz and Kurths, J{\"u}rgen}, title = {Noise induced propagation in monostable media}, year = {2002}, abstract = {We show that external fluctuations are able to induce propagation of harmonic signals through monostable media. This property is based on the phenomenon of doubly stochastic resonance, where the joint action of multiplicative noise and spatial coupling induces bistability in an otherwise monostable extended medium, and additive noise resonantly enhances the response of the system to a harmonic forcing. Under these conditions, propagation of the harmonic signal through the unforced medium i observed for optimal intensities of the two noises. This noise-induced propagation is studied and quantified in a simple model of coupled nonlinear electronic circuits.}, language = {en} } @article{ZaikinGarciaOjalvoSchimanskyGeier1999, author = {Zaikin, Alexei A. and Garcia-Ojalvo, Jordi and Schimansky-Geier, Lutz}, title = {Nonequilibrium first-order phase transition inducd by additive noise}, year = {1999}, language = {en} } @article{ZaikinSchimanskyGeier1999, author = {Zaikin, Alexei A. and Schimansky-Geier, Lutz}, title = {Ordering role of additive noise in extended media}, issn = {1373-5411}, year = {1999}, language = {en} }
