Seeing the Real Atomic Correlation in Matter
Abstract
Bragg's law is an ultimate magic, because it reduces the positions of 10(23) atoms to just a few numbers. This, of course, is a lucky consequence of translational symmetry. Unfortunately, we are not always lucky with many materials that are important today, including ourselves (biological matter), since they (and we) are not crystalline, or only poorly crystalline. But it is possible to see, more or less directly, the real atomic correlations in these disordered matters by using the method of atomic pair-density function (PDF) analysis using neutron or x-ray scattering. Due to advances in instrumentation we now can determine the PDF up to 20 nm, and see even the dynamics of correlation by the dynamic PDF method. This talk will address some examples of this approach facilitates understanding of complex matter, and where the field may be heading.
