Many of the properties of a material depend more on the dynamics of its\u00a0microstructure than on its atomic structure. Photon correlation\u00a0spectroscopy (PCS) is an ideal way to study temporal fluctuations of\u00a0this microstructure and by using laser light, it has been used since the\u00a0late 1960s. These techniques has recently been extended to the x-ray\u00a0region (XPCS). This allows one to study opaque materials and more\u00a0importantly, to probe much shorter length scales such as required to\u00a0study metal alloys. By the use of high resolution x-ray area detectors,\u00a0XPCS is also being used to study systems with much longer time scales\u00a0and to study fluctuations in non-equilibrium systems using two-time\u00a0correlation functions. We have also extended XPCS by using heterodyning\u00a0which allows us to probe local flow as well as dissipation.<\/p>\n

This talk will describe XPCS using ideas from statistical mechanics and\u00a0optics and will present several examples. It should be easily accessible\u00a0to upper year undergraduates and graduate students in physics.<\/p>\n
