Abstract
It is shown that a paradigm of classical statistical mechanics—the thermalization of a Brownian particle—has a low-dimensional, deterministic analog: When a heavy, slow system is coupled to fast, deterministic chaos, the resultant forces drive the slow degrees of freedom toward a state of statistical equilibrium with the fast degrees. This illustrates how concepts useful in statistical mechanics may apply in situations where low-dimensional chaos exists.Keywords
