Research output: Contribution to journalConference articlepeer-review


A brief review of the underlying principles of diffusing-wave spectroscopy is given, and direct measurements of the path-dependent correlation function are described. In addition we introduce experiments to probe particle motion on very short length (<2 angstroms) and time (<10 ns) scales, and discuss recent measurements of structure and diffusion in dense binary hard sphere fluids.
