We report the results of studies of nonlinear dynamics and dynamical chaos in Hamiltonian systems composed of many interacting particles. The importance of the Lyapunov exponents and the Kolmogorov-Sinai entropy is discussed in the context of ergodic theory and nonequilibrium statistical mechanics. Two types of systems are studied: hard-ball models for the motion of a tracer or Brownian particle interacting with the particles of a surrounding fluid and microplasmas which are composed of positively charged ions confined in a Penning electromagnetic trap. Lyapunov exponents are studied for both classes of systems. In microplasmas, transitions between different regimes of nonlinear behavior and chaos are reported.
