There is a growing recognition that ecological systems can spend extended periods of time
far away from an asymptotic state, and that ecological understanding will therefore require a …

Dynamical systems may experience undesirable behavior or instability, which can be
eliminated using feedback control means. However, in the absence of feedback control, the …

Nonlinear relaxation phenomena in three different systems of condensed matter are
investigated.(i) First, the phase dynamics in Josephson junctions is analyzed. Specifically, a …

Noise-induced phenomena characterise the nonlinear relaxation of nonequilibrium physical
systems towards equilibrium states. Often, this relaxation process proceeds through …

We study by numerical methods the phase dynamics in ballistic graphene-based short
Josephson junctions. A superconductor-graphene-superconductor system exhibits …

We numerically investigate the generation of solitons in current-biased long Josephson
junctions in relation to the superconducting lifetime and the voltage drop across the device …

We investigate the superconducting lifetime of a long overdamped current-biased
Josephson junction, in the presence of telegraph noise sources. The analysis is performed …

Normally, quantum fluctuations enhance the escape from metastable states in the presence
of dissipation. Here we show that dissipation can enhance the stability of a quantum …

We investigate the superconducting lifetime of long current-biased Josephson junctions, in
the presence of Gaussian and non-Gaussian noise sources. In particular, we analyze the …

Finite-size effects may significantly influence the collective dynamics of large populations of
neurons. Recently, we have shown that in globally coupled networks these effects can be …
