dc.description.abstract | Multistability, i.e., the coexistence of several attractors for a given set of system parameters,
is one of the most important phenomena occurring in dynamical systems. We consider it in the
velocity dynamics of a Brownian particle, driven by thermal fluctuations and moving in a biased
periodic potential. In doing so, we focus on the impact of ergodicity—A concept which lies at the core
of statistical mechanics. The latter implies that a single trajectory of the system is representative for
the whole ensemble and, as a consequence, the initial conditions of the dynamics are fully forgotten.
The ergodicity of the deterministic counterpart is strongly broken, and we discuss how the velocity
multistability depends on the starting position and velocity of the particle. While for non-zero
temperatures the ergodicity is, in principle, restored, in the low temperature regime the velocity
dynamics is still affected by initial conditions due to weak ergodicity breaking. For moderate and
high temperatures, the multistability is robust with respect to the choice of the starting position and
velocity of the particle. | pl_PL |
