Stochasticity can play an important role in the dynamics of biologically relevant populations.
These span a broad range of scales: from intra-cellular populations of molecules to …

The physics of non-equilibrium many-body systems is a rapidly expanding area of
theoretical physics. Traditionally employed in laser physics and superconducting kinetics …

Stochastic differential equations play an increasingly important role in modeling the
dynamics of a large variety of systems in the natural sciences, and in technological …

The book provides a unifying insight into fluctuation phenomena in a broad variety of
vibrational systems of current interest. It consists of individual chapters written by leading …

Experimental observation of the unidirectional motion of a topological soliton driven by a
biharmonic ac force of zero mean is reported. The observation is made by measuring the …

We investigate disease extinction in an epidemic model described by a birth-death process.
We show that, in the absence of vaccination, the effective entropic barrier for extinction …

The physics of critical phenomena in a many-body system far from thermal equilibrium is an
interesting and important issue to be addressed both experimentally and theoretically. The …

We have realized a Brownian motor by using cold atoms in a dissipative optical lattice as a
model system. In our experiment the optical potential is spatially symmetric and the time …

The measurement of the escape time of a Josephson junction might be used to detect the
presence of a sinusoidal signal embedded in noise when use of standard signal processing …

The extinction time of an isolated population can be exponentially reduced by a periodic
modulation of its environment. We investigate this effect using, as an example, a stochastic …
