dc.description.abstract | We study barrier crossing of Brownian particles in a bistable symmetric
potential and transport of Brownian particles in spatially periodic structures,
driven by both kangaroo fluctuations and thermal equilibrium noise
of zero mean values. We consider exponentially and algebraically correlated
kangaroo fluctuations. Starting with the full Newton-Langevin equation for
the Brownian particle and by introducing scaling as well as dimensionless
variables, we show that the equation is very well approximated by overdamped
dynamics in which inertial effects can be neglected. We analyze
properties of selected macroscopic characteristics of the system such as the
mean first passage time (MFPT) of particles from one minimum of the
bistable potential to the other and mean stationary velocity of particles
moving in a spatially periodic potential. In dependence upon statistics of
kangaroo fluctuations and temperature of the system, macroscopic characteristics
exhibit distinctive non-monotonic behavior. Accordingly, there
exist optimal statistics of fluctuations optimizing macroscopic characteristics. | pl_PL |
