When a wire is connected across a battery, energy is transferred from the macroscopic electrochemical potential difference of the battery terminals to the disorganized, microscopic degrees of freedom of the electrons and vibrational motions of the wire constituents. How does this process work when the critical part of the "wire" consists of only a few atoms? Atomic- and molecular scale junctions enable experiments to examine quantum systems driven far from equilibrium. I will present measurements of shot noise and single-molecule Raman scattering in such junctions, experiments that provide information about the evolution of the local electronic and vibrational distributions in biased junctions. I will discuss the implications of the data and prospects for future investigations of more complex quantum systems away from equilibrium.
