An origin of 1/f fluctuations at a nonequilibrium phase transition

Koverda, V.P.; Skokov, V.N. - In: Physica A: Statistical Mechanics and its Applications 262 (1999) 3, pp. 376-387

We present the results of experimental study of an intensive source of wide-band 1/f noise whose generation appears in a system of two interacting nonequilibrium phase transitions. Such a process has been realized in the region of superposition of a superconductor–normal conductor phase...

Collective behavior of coupled nonuniform stochastic oscillators

Assis, Vladimir R.V.; Copelli, Mauro - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 4, pp. 1900-1906

Theoretical studies of synchronization are usually based on models of coupled phase oscillators which, when isolated, have constant angular frequency. Stochastic discrete versions of these uniform oscillators have also appeared in the literature, with equal transition rates among the states....
