Brownian motion: Anomalous response due to noisy chaos

We predict three different, quite unusual transport properties of an underdamped Brownian particle in the form of current and force of opposite signs. Their origin is a subtle interplay between the stability of coexisting attractors, noise-induced metastability, and transient chaos. Numerical simulations are complemented by intuitive explanations of the basic mechanism and analytical approximations.
